I just restarted my server and tried to pull the update and it didn't pull. I also tried the other suggestion of validation in the template from true to false then restarted the container than back to true and restarted. It's not pulling an update. I don't have anything else on my network such as adblocking. All other docker containers are able to pull updates just fine but not Valheim.
Here is the log
text error warn system array login
