I keep getting a “The server has reached end of life, please upgrade” message when I start Nextcloud on Android. I keep my MiaB instance updated but I don’t do anything special with Nextcloud. Is this a MiaB or Nextcloud problem?
(Nextcloud on Android is very janky also but I’m 90% sure that’s my overagressive firewall.)
Yeah, the nextcloud version is getting pretty long in the tooth. Unfortunately, development is a bit stuck in that area. I won’t bore you with the details, look in github for php if you’re interested 
@KiekerJan Okay, thanks, that’s a bit too complicated for me. I could try downgrading my Nextcloud client on Android for the meanwhile, if this is why it takes ages to connect to the server.
Could I or any of my users be using Nextcloud inadvertently or automatically? I’m not sure why it’s included, actually, so unless there is some internal dependency, it simply disappearing would not impact my lot.
It’s included in Mail in a Box to provide synchronized calendar and contacts. If you’re using the nextcloud app, you might be using it for that. Nextcloud also provides file sharing. Again, you might be using that functionality via the app.
As far as I know, you need to setup using any Nextcloud functionality, but it might be simply clicking yes in some autoconfiguration window.
OK, so if I asked my users and none report using any of those feature, I’m in the clear? Is there a way to check on the system itself for signs of people using it you know of?
That sounds right. But I just remembered that the webmail is configured to synchronize contacts with nextcloud. So if peoole have contacts in there, they are using nextcloud.
I would have to dig. There might be evidence in the mail.log file (nextcloud uses imap for authentication) or you could have look at the nextcloud database file. It’s accessible using the sqlite3 tool, but I don’t know the table structure.
