Ok my confusion is around what entries are actually needed in the env file.
My initial .env file used:
aliasgroup1=https://cloud.domain1.com:443,https://cloud\.domain1\.com:443
aliasgroup2=https://cloud.domain2.com:443,https://cloud\.domain2\.com:443
Worked fine initially, but now getting the unauthorized wopi host error when trying to open documents.
So I searched and found a few other syntax examples, so changed it to use:
COLLABORA_FQDN=code.domain1.com
COLLABORA_DOMAINS=cloud.domain1.com|cloud.domain2.com|cloud.domain3.com
I have seen a few different variations of variable names, but not certain which ones I need to use to get past the wopi host errors.
I can share more detail with the config and logging, but I think the issue is with the .env file and these domain values?
I followed the steps in this thread: Yet another problem with Nextcloud Office/Collabora - #2 by kevdog
I have seen some suggestions to put the IP address in for the values as well.
Can someone school me on the correct variables to use when accessing Collabra from separate nextcloud domains?
Thank you
