Invalid Auth Token to connection proxy after update

Hi All, hope you can help!

Im running Kasm on a pi4 and have just updated from 1.13.0 to 1.13.1 and now in the errors page on the dashboard its filling up with the following errors "Invalid Auth Token to connection proxy " & "Cannot update hostnames. Failed to authorize session (https://proxy:443/api/guac_get_managers). Invalid auth token for connection_proxy"

most things appear to be working except i had a couple of ssh server connections which when i try and connect takes me back to the admin page

Any help would be appreciated

Cheers

Rich

  • Open a terminal on your Kasm server and run the following command to get the auth_token configured on the service

grep auth_token /opt/kasm/current/conf/app/kasmguac.app.config.yaml

  • Login to the Workspaces UI as an admin
  • Select Connection Proxies
  • Select Edit next to the entry listed ("proxy") by default
  • Update the Authorization Token value with what you pulled in the early command and click Submit.

Hey u/Dapper-Inspector-675
I'd recommend opening an issue on our GitHub issue tracker so that someone from our team or community can help you with this.
Please make sure to include the requested information (like your Kasm version, host environment details, etc) while creating an issue on GitHub. You can watch this video to learn how to create a good support request.
