After auto update to ncp 1.47.2 nextcloud not availale from internet

[/details]

Nextcloud version : 20.0.8.1
NextCloudPi image : NextCloudPi_10-08-21
Operating system and version : Debian GNU/Linux 10. 5.10.103-v8+ (aarch64)
Apache or nginx version : Apache/2.4.38 (Debian)
PHP version : 7.3

Hello there,
After the automatic update to NextCloudPi v1.47.2 three weeks ago my NextCloud instance was not available from the internet anymore. From inside of my network (LAN) the NextCloud instance is available, but the browser warns from the use of an untrustworthy web site, because the certificate is made for the hopto.org site, that should be available from the internet, so I think, this is a normal behavior. The reason, why i cannot access the NextCloud instance from the internet, is that in the System info of the NextCloud web admin panel there is the information that the ports 80 an 443 are closed. But this is not true, because if I check this on my router (FritzBox) the ports are open but not used. Before the auto update to v1.47.2 everything worked “fine” and I haven’t made any changes to the network configs. After the update the ports are not used now.
If you need more logfiles, so let me know. But tell me, where can I find them, because i’m not that Lunix Guru.

Is this the first time you’ve seen this error?: Y

Is it possible to update the system?
So if you manually try to update in ncp-config does there occur any failure?
Just to be sure that there is no generell internet connection issue with your ncp-device.

The mistake in showing the ports closed is known. Same with my instance, but everything works normal.

I have ping’ed Google, all transmitted packages were received, no packages lost.
What do you mean with update the system, do you mean update ncp or the nextcloud instance? Form ncp-config i tried to update the current NextCloud instance and received the information “Upgrade cannot skip major versions. Please update one major version at a time”.
On my Android device and the i/OS device of my wife there are also problems. On my Android device DavX5 shows that there is an I/O Error for the connection and on the apple device calendar entries are not synchronized with the ncp, same on android. So in our family we are back to the paper calendar :frowning:

I have the same issue but I have nc version 23.0.2.1

This is my ncp-report output

https://pastebin.com/1pa4pr7K

could you please tell me, which option do I have to choose in ncp-config to trigger an update of the system?

You have the option “update” to update the ncp version. “Nc-update” triggers the Nextcloud updates. And the there is nc-app update (not sure about the name) to update the apps. All the options can be SRT to autoupdate or not.

Ok, I used the option Update NC apps. The update of the apps was successful. What to do now?

I solved the problem with this information

I seems that it was a error with the corrupted file system
