I updated to PHP 7.3.20 and now I can't log in anymore

I also switched to PHP 7.4.8 and I got NC to work. Is this issue specific to PHP7.3.20?

Is Nextcloud in PHP 7.4 working stably anymore?
Should I take this opportunity to switch to a PHP 7.4 environment?

I’ve been using 7.4 with no issue.

Seem like 7.3 is NOT compatible with nextcloud.

PHP 7.3 is working like a charm with Nextcloud. In most cases users are forgetting to install all required or removing all legacy components or are not configuring their PHP environment in the right way.

You have a problem with php-fpm (FastCGI Process Manager). Users of Apache doesnt need this. All command lines with a2dismod or apache module are useless.

When you updated php, did you say “yes” when the updater offered to keep the configuration files of the developer ?
First, check that php7.3-fpm is running : systemctl status php7.3-fpm

Same problem here. Nextcloud with php 7.3.20 fpm broken.
It worked before flawlessly with php 7.3.19.
I upgraded from latest nc 18 to latest nc 19, still broken.

Welcome page works, login not possible.
“Nice” error message:
“proxy_fcgi:error *** Connection reset by peer: *** AH01075: Error dispatching request to :”
(after the last “:” there is just nothing.)

I’m loving it!

I’m having the same issue. Upgraded to php 7.3.20 yesterday. Now I can’t login to Nextcloud or use the dav-API. Same issue with 7.2.32. Nextcloud was working perfectly with 7.3.19.

This is the error message in the logs.

If you’re in a hurry to solve the problem, you’ll have to switch to PHP 7.4.
I made a hasty switch to PHP 7.4, but I still don’t understand the downside.

For various reasons, I cannot go to php 7.4 easily on that server.
I also do not understand the problem. All other Webapplications work fine on that server, with the very same php configurations. Just nextcloud does not work with latest 7.2.X and 7.3.X (I tested both now).

I’m still running Nextcloud 17. According to the system requirements 7.4 is not supported.

@khujo i suggest a solution for your special usecase: upgrade to v18 via console should work on php 7.3, i did myself an upgrade from 18 to 19 “manually” (I stopped using webupdater in general, as it works not that often without flaws).
Then you could switch to php 7.4 maybe, if your server supports that.

I’ll try that. Thank you!

Anyone up with a solution already for nextcloud with php 7.3.20?

I havent had the exact problem. However when I first upgraded to PHP7.4 I had some issues that caused segfaults in php-fpm. It seems that some apps/extensions are a bit buggy and need to be disabled (occ app:disable). For me I’ve had issues with radio, maps, bookmarks and other apps using guzzlehttp library.

the problem does not occur because of the PHP version, but only on some servers. e.g. for me with plesk-php-7.2 and 7.3.
Solution: manually install your own PHP (also possible in Plesk) and everything works.

I have this very same problem.
Today the 18.0.7 nextcloud update came out. I installed, and I could log in again. For about 5 minutes, then it went back to “Service unavailable”

@Gjimi How do I install my own PHP in plesk? Any help appreciated!

Please open an own thread with all details. I think your problem differs from the problem in this thread.

e.g. that’s 2 min. in Debian 9.

  • to run:
    wget -O - https://www.liveconfig.com/liveconfig.key | apt-key add -

  • edit apt/source.list:
    deb [arch=amd64] http://repo.liveconfig.com/debian/ stretch php

  • install own PHP
    apt-get install php-7.3-opt-ldap php-7.3-opt-apcu php-7.3-opt-imagick php-7.3-opt-ioncube php-7.3-opt-redis

  • Adjust settings like php.ini if necessary, /opt/php-7.3/etc

  • (e.g. file_uploads = On)

  • Add PHP Handler to Plesk

  • run:
    /usr/local/psa/bin/php_handler --add -displayname “7.3 custom” -path /opt/php-7.3/bin/php-cgi -clipath /opt/php-7.3/bin/php-cgi -phpini /opt/php-7.3/etc -type fastcgi -id “PHP7.3_custom”

With Debian Buster 10 there are no problems with the php-version. Perhaps you dist-upgrade to Debian Buster 10. Debian Buster 10 was released more than a year ago.

Debian Stretch 9 has only LTS support.


I tried nextcloud-18.0.7 with php-7.3.20 without issue.

Remember to clear opcache folder
