Hubzilla Support Forum,
as a Newbie in Hubzilla, but experienced "LEMP user", I am trying to establish an own hub on my domain rkor.info, but I am fighting with some irregularities, especially as it comes to the Diaspora protocol. The most striking thing is, that I see uncaught PHP exceptions as soon as I activate the addon
Diaspora Protocol, which typically looks like this (with the last 6 lines showing the "cronjob" of Hubzilla based on a systemd timer):

I switched on the error logging in .htconfig.php once, and received about 80 of these exceptions in 1.75 hours.
As you can see, I am trying to run it on a LEMP stack (which serves different other services successfully). It is possible - but not that likely - that I messed up something in the php.ini. But all the other things should follow the requirements in the documentation:
- Up-to-date Arch Linux with PHP 7.0.32 (from the AUR) and 7.2 (the uncaught exception is not depending on the PHP version), opcache is on. I do not know how to check the exec() and proc_open() thing easily, but it is a standard Arch Linux on a KVM, so I would not expect such restrictions.
- Almost latest Hubzilla 3.8.6 with manual install as described in the documentation, updates as described there seem to work normal.
- PHP requirements checked using phpinfo (php-imagick not present, but marked optional in the docs)
- Further requirements, especially writability of directories, checked and ok.
- The nginx configuration is taken from here (I am aware of the sample config in install, which seems to be more adapted to PHP5) with minor modifications, the systemd timer from here.
I am observing further oddities, which might be related to that:
- I have started a second channel @Robert Kormann on the established hub hubzilla.eu, I can contact fine from here to there using Zot as network, however, the opposite direction is leading to the protocol Diaspora (if it is switched on). Trying to enforce it using [zot]channel@hub leads to channel not found.
- I tried to connect to a well-known German blogger, who uses Hubzilla and writes regularly, but the connections on both hubs are marked with network Diaspora and got never updated (although there are newer items). Same story with trying to enforce Zot.
- The Addons PubSubHubBub and PubCrawl are activated, but I never managed up to now to connect to a Mastodon account.
So, any help would be very appreciated, especially since I like all the other stuff I see. However, Hubzilla should be the entrance gate into the fediverse, not only into parts of it. I can provide more technical information, if needed. Thank you very much in advance.
Robert
