Failed to get latest version HytaleServer.jar

[l4ci]

I just started the docker image on my ugreen nas and after authenticating I get the following error:

I did not download anything else, just started the container and authenticated - shouldn't this download the files automatically?

Hi @l4ci
Yes it should.
Can you try deleting server-files/downloader/.hytale-downloader-credentials.json?
Then reboot the container, it should prompt you for auth again.

Hi @indifferentchicken ,

it did ask me for the auth again - and afterwards I get the error message:

I did remove the Auth code, just in case it might be sensible.

I am having the same problem, did you find a fix?

[l4ci]

I tried another docker image deinfreu/hytale-server, which seems quite popular as well - but its the same error there. So it might be related to my specific setup or the general installer.

Yeah mine is currently saying:

hytale  | Machine ID configured for encrypted auth persistence
hytale  | ====Checking server version====
hytale  | Running on x86_64 architecture
hytale  | Checking latest version...
hytale  | Failed to get latest version

and its stuck in a restart loop

@dillfrescott
Can you delete the .version file and .hytale-downloader-credentials file and restart the container? More than likely you just need to reauth.

Hey guys, I changed my DNS to 9.9.9.9 on my server and it just works now. Hope this works for you aswell.

[Nukehead]

I had the same problem. I solved it by flushing the dns resolver cache, deleting the .version and the .hytale-downloader-credentials file. Then I restarted the container, the update check required a new oauth token and then it updated the game and started the server. I don't know if emptying the dns resolver cache was necessary, but with the comment about changing dns server I thought it may help too.
