Describe the bug

When trying to upgrade the adapter via the adapters page, a Networkerror occurs and I have to login to console and restart the admin adapter.

TypeError: NetworkError when attempting to fetch resource.

There is nothing in the logs.

The upgrade of admin worked reliably before but started to fail end of last year. Not sure with what version. I didn't care because upgrade still worked from info adapter.

To Reproduce

Go to Adapters page. Click the button with the new version for admin adapter. A few sec later the modal with the error appears.

Expected behavior

admin adapter upgrades as other adapters.
