Hey folks,

i have a problem, i installed an valheim server with the umod agent on my root server (win). First everything works fine but, 

after i restart the the server a couple of times to update the plugin configs i got an error when i try to start the server.

I coudn't find out why and i deleted all files and reinstall umod agent to installed a clear new server, but if i try to start the server, i got the same error (without plugins) and the server starts without umod.

Error:

[uMod] 03:28 [Error] Checksums do not match: valheim.zip
[uMod] 03:28 [Error] Failed to download resource: Valheim - Checksums do not match: valheim.zip
[uMod] 03:28 [Error] Core update failure

My commands to install the server:

For Win:

&powershell -NoProfile -ExecutionPolicy unrestricted -Command "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12;&([scriptblock]::Create((Invoke-WebRequest -UseBasicParsing 'https://umod.io/umod-develop.ps1')))"

cd C:\Valheim (my path where i want to install the server)

umod install valheim -P ( with same error at the end) 

umod new launcher -P

and do my config stuff to set the server and start him:

valheim_server.exe -nographics -batchmode -name "XXXXX" -port 27000 -world "XXXXX" -password "XXXXX" -public 1

Thanks for every help

EDIT:

I delete now the following part from the launcher.bat

update game core apps extensions

unzip the valheim.zip and copy the files to the correct place, now the server starts fine with all plugins. 

Something runs wrong to match the hash, when umod tryes to update the game/umod

Try using 'umod update -P --force'

Wulf

Try using 'umod update -P --force'

Same error :/ with PowerShell and CMD

Try using 'umod update -P --force'

Now it works without probelms, but i didnt change anything. I tryed it only again, like 100 times bevore. Maybe an umod-server issue?

Never mind thanks anyway!

EDIT:

Now i have a different error but without error massage
