Webfinger/nodeinfo/invalid hash

I have the ‘invalid hash’ problem and webfinger/nodeinfo on all new installs (runcloud: )
sometimes only index.html, sometimes also the htaccess. (random)

I tried a lot to repair it but to no avail. Also ‘did’ some topics here. And a ticket to Runcloud helpdesk.

3 questions:

  1. is it safe to continue work and go use the nextcloud install for this business. or: what problems might I face on long term if I do this?

  2. are there faults in the 2 years old Runcloud instructions https://blog.runcloud.io/nextcloud/ which might lead to this?

  3. Maybe, just maybe someone with some spare time wants to login to my runcloud/Hetzner instance to have a look around?
