Nextcloud version (eg, 20.0.5): 23.0.4
Operating system and version (eg, Ubuntu 20.04): Ubuntu 20.04.4
Apache or nginx version (eg, Apache 2.4.25): nginx/1.18.0
PHP version (eg, 7.4): 8.0.19
Just since this morning I cannot connect to my nextcloud via the browser or client. In the browser I get “The connection has timed out” in the desktop client it indicates “Offline”. The Android client just hangs with the spinning circle.
A strange (to me) thing is that my Uptime Doctor email notifications show that it is UP occationally. The most resent notification told me that the site was DOWN for 01hr 15min, but when I attemt to connect (as soon as I got the email notifiation) I still got the “The connection has timed out” message.
EDIT: Another strange thing is I can connect with ssllabs.com and get an “A” rating. But with a warning that " HTTP request to this server failed, see below for details."
The detail is that:
https://www.domain.net/ (Request failed)
Just to be sure I checked that my ports were still open using ‘nmap localhost’ and that does not seem to be a problem:
Starting Nmap 7.80 ( https://nmap.org ) at 2022-06-06 13:13 EDT
Nmap scan report for localhost (127.0.0.1)
Host is up (0.0000080s latency).
Other addresses for localhost (not scanned): ::1
Not shown: 991 closed ports
PORT STATE SERVICE
22/tcp open ssh
80/tcp open http
443/tcp open https
631/tcp open ipp
3306/tcp open mysql
3551/tcp open apcupsd
4000/tcp open remoteanything
7001/tcp open afs3-callback
20000/tcp open dnp
Nmap done: 1 IP address (1 host up) scanned in 0.14 seconds
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- navigate to my nextcloud domain, or open a nextcloud client
The output of your Nextcloud log in Admin > Logging: Since I can’t access the instance I output occ log:tail instead, listing only events since yesterday (when everything was working just fine).
