[MCL-11270] Unable to Login To Launcher

Attempting to login with the Launcher fails with the console reading SaveToBuffer failed. Additionally, if the user was already signed and then performed the launcher update the launcher would proceed to advance past the login screen only to say the user has no connection. This issue has persisted since the move to the new launcher versions.

Please attach the launcher_log.txt file here.

I am having this issues and I even re downloaded the client and installed it from the site to be sure as well.

TechdudeGames 2019-06-29T20:02:59Z

I added the launcher log, mine is the one with the underscore before the other text.

I was unable to upload it unless I changed the name.

Alan McClure 2019-06-29T20:05:05Z

As a matter of fact all the entry windows in the Edit Installation dialog are too small.
I define a Game directory for each major Release and the path just to .minecraft is longer than the dialog will allow you to see without scrolling.
Same for Java executable and JVM arguments.
It would help if they were on separate lines like they were in the old launcher and also if the dialog box would expand horizontally with the launcher window.

[Mod] violine1101 2019-06-29T20:09:44Z

@unknown, that's completely unrelated to this issue.

Alan I am not entirely sure how your post relates to this issue specifically, could you explain what you mean about the Edit Installation dialog box? Is that an option in the Launcher on Linux?

TechdudeGames 2019-06-29T20:21:37Z

I think he meant to comment on that on MCL-11253 but accidentally commented it here

Lostic 2019-06-30T18:28:12Z

I used to have this issue recently and what I did to fix this issue is by re-logging my account on the new minecraft launcher. This should fix the constant "no connection" error every time you try to refresh it. Have you tried re-logging (log out and log back in minecraft launcher)?

TechdudeGames 2019-06-30T20:49:27Z

Lostic I tried that but on Linux even with a fresh install with no added accounts and no launcher_profiles.json file it still refuses to log in with the console reading still "SaveToBuffer failed"

TechdudeGames 2019-06-30T20:53:08Z

I updated my _launcherlog.txt file that shows the error.

Vít Pokorný 2019-07-04T15:16:53Z

i have literaly the same problem. i found that if you change password it lets you log in once but then it fails agin

Gus Scheidt 2019-07-06T01:00:59Z

I can confirm that I see this same behavior.

I was originally logged in from the previous version of the launcher and had the "No connection" message and only the "Play Offline" option. I logged out and now am unable to log back in with the message "Sorry! Make sure you are online and try again", with the "SaveToBuffer failed" message in the console.

Gus Scheidt 2019-07-06T13:18:16Z

I don't know if this is helpful or not, but I used wireshark to capture network traffic during the period of time that I clicked the "LOG IN" button on the Add account modal on the Accounts setting tab. It appears as though a TCP connection was established to authserver.mojang.com and then immediately closed without sending any data. No other related network traffic was captured.

TechdudeGames 2019-07-08T04:08:40Z

What is the wireshare capture after you changed the password and logged in again?

brickviking 2019-07-13T08:58:10Z

Specs: Fedora Linux 27, 4Gb memory, 64-bit E8400 (Core/2 Quad core), ATI Radeon 3450.

In addition to the other respondents,

I occasionally have the "SaveToBuffer Failed" message in my console
I still appear to be logged in
I can still play online Minecraft.

I haven't been brave enough to log my user out in the Launcher, as I'm not sure I'd get back on. I also haven't been able to pin down why the message is only happening occasionally for me.

Regards, BrickViking

Gus Scheidt 2019-07-13T15:17:21Z

The wireshark capture is the same after changing the password. Logging in after password reset does not work for me.

slicedlime 2019-07-15T11:15:08Z

According to the logs, this is your system is rejecting the server's SSL certificate. This could indicate some form of error in your installation of libcurl, or something similar.

Could you try downloading this file with curl, and see if that works?

curl https://launchermeta.mojang.com/mc/game/version_manifest.json

TechdudeGames 2019-07-15T22:04:30Z

I can run curl correctly and download the file (When I pipe it to version_manifest.json via ">". Otherwise it just prints to stdout). I made sure it was in the .minecraft directory but the error persisted.

Gus Scheidt 2019-07-15T23:44:46Z

That curl command is also runs successfully for me.

I assume that if it were a system problem that it would also have surfaced with the old launcher. This problem only started with the most recent launcher.

William Stapel 2019-07-23T16:05:51Z

Count me in among those with this issue. The previous launcher worked and curl downloads the file, but the new launcher won't allow me to log in, giving the SaveToBuffer failed message, even after removing the .minecraft folder entirely.

Gus Scheidt 2019-09-03T14:13:07Z

Any way to get this issue escalated? It is a show-stopper. It prevents installation of any version of MC. If some version of MC was not already installed using a previous version of the launcher, there is literally no way to play on Linux. Even if there is an existing version of MC installed, there is no way to play online and no way to install a newer version of MC.

marcneander 2019-09-23T16:02:43Z

We've done some improvement to linux users in the new Beta version. If you're willing to test out the beta you can find download links here (Article is old, but links are still valid):

https://www.minecraft.net/en-us/article/try-new-minecraft-launcher-beta

Petter Karkea 2019-09-23T16:13:09Z

Still not working. Downloaded the .deb from the link provided to the beta launcher.

Marc, thank you for the update.

Unfortunately, I installed the 2.1.7658 version of the launcher from the beta page and the behavior is the same. (I tried both the .deb file and the .tar.gz file.)

petr.mrazek 2019-09-24T08:24:06Z

What output do you get when you run:

curl -v https://launchermeta.mojang.com/v1/products/launcher/6f083b80d5e6fabbc4236f81d0d8f8a350c665a9/linux.json

And yes, install the package if it's missing first.

Petter Karkea 2019-09-24T08:27:45Z

Running on the previously installed Beta package and getting this:

Hmm, please attach the whole strace from just starting and closing the launcher.

strace -f minecraft-launcher > strace.log 2>&1

Also, what does the /etc/ssl/certs/ca-certificates.crt file look like? It should exist and contain a whole bunch of base64 encoded data.

Can you share the file too, if it exists?

I installed the same distro and cannot reproduce the issue. One discrepancy is that on your system, it is loading /usr/lib/x86_64-linux-gnu/libcurl.so instead of /usr/lib/x86_64-linux-gnu/libcurl.so.4

So, let's find out where that comes from:

dpkg -S /usr/lib/x86_64-linux-gnu/libcurl.so

And what it depends on:

readelf -d /usr/lib/x86_64-linux-gnu/libcurl.so
ldd /usr/lib/x86_64-linux-gnu/libcurl.so

Removing libcurl4-nss-dev and libcurl3-nss should fix the problem.

petr.mrazek 2019-09-24T10:09:09Z

The root of the issue seems to be that the nss-based libcurl is using outdated certificates baked into libnssckbi.so. This doesn't work.

Petter Karkea 2019-09-24T10:16:20Z

Now it seems to work! Tested login, downloading latest stable (1.14.4) and played on a server. Ran this on my Linux Mint 19.2 Tina (Ubuntu 18.04, Bionic Beaver):

$ sudo apt remove libcurl4-nss-dev libcurl3-nss

$ sudo apt remove libcurl4-nss-dev libcurl3-nss

Gus Scheidt 2019-09-24T10:51:33Z

I can confirm that removing libcurl4-nss-dev and libcurl3-nss resolves the issue.

My guess would be that the reason you could not replicate this problem on a fresh install of the distro is that these packages are probably an artifact of upgrading from a previous version of the distro.

Unfortunately, there are probably many people in this situation. It would be ideal if you could update the launcher to handle the case when these packages are installed.

petr.mrazek 2019-09-24T11:33:20Z

Yeah. We just need to be more specific about the libcurl we want from the system.

Shouldn't be too hard to fix 🙂

petr.mrazek 2019-09-24T11:44:59Z

Can you test with this one?

Petter Karkea 2019-09-24T12:01:05Z

Ran this:

$ sudo dpkg --purge minecraft-launcher
$ sudo apt install libcurl4-nss-dev libcurl3-nss
$ sudo dpkg --install minecraft-launcher-libcurl-fixed.deb
$ minecraft-launcher

$ sudo dpkg --purge minecraft-launcher
$ sudo apt install libcurl4-nss-dev libcurl3-nss
$ sudo dpkg --install minecraft-launcher-libcurl-fixed.deb
$ minecraft-launcher

Worked great: started the launcher and logged in.

Gus Scheidt 2019-09-24T12:35:13Z

Confirmed that version 2.1.7698 from "libcurl-fixed" runs properly when libcurl4-nss-dev and libcurl3-nss are installed. I can log in and play online.

Many thanks for the work on this!

TechdudeGames 2019-09-24T16:34:04Z

I will check that version of the launcher when I get home, but I am optimistic given the others success getting it working! Thank you for helping to fix this issue! I appreciate it.

TechdudeGames 2019-09-25T00:58:06Z

I can verify that the "libcurl-fixed" version is also working for me! Will this fix be implemented into the regular launcher deb file in new releases?

Nonetheless, thank you Petr Mrázek for helping to fix the issue!

Aljaz S. 2019-10-29T08:09:30Z

Red flag :flag_on:

I ran into this issue after I updated to the latest release.

@Aljaz S. No, you ran into mods being broken and abusing Java internals. That has nothing to do with this issue.

You will have to use Java 8 with modded and old versions. Anything above 8 will not work.
