I got some debugging info. There is now an INFO message with "valid HTTP signature". But I cannot find the post in the helpers group.

The log for the request-id is pretty long. So I have stored the line in a file and uploaded it.

@fossfan Yep. But we excluded this from the list of possible issues. 😀

I still see this message:
2026-07-31T09:45:02Z app [NOTICE]: Invalid HTTP signature, message will not be trusted. {"uid":0,"actor":"https://friendica-sverige.se/profile/leanderlindahl", ... ...

I guess this check in ActivityPub\Receiver.php is failing:

115    $http_signer = HTTPSignature::getSigner($body, $header);
116    if ($http_signer === false) {
117        DI::logger()->notice('Invalid HTTP signature, message will not be trusted.', ['uid' => $uid, 'actor' => $actor, 'header' => $header, 'body' => $body]);
118        $signer = [];

@heluecht Any idea when and why this happens?

@fossfan I can see messages in the logs of forum.friendi.ca:

2026-07-31T04:55:01Z app [NOTICE]: Invalid HTTP signature, message will not be trusted. {"uid":0,"actor":"https://friendica-sverige.se/profile/leanderlindahl", ... ...

At a first glances I can tell that your server is communication via IPv6 with forum.friendi.ca. But there is no AAAA DNS record for your IPv6 (2a01:4f9:c015:6d88::1).

root@forum:~# host friendica-sverige.se
friendica-sverige.se has address 65.109.12.183
friendica-sverige.se mail is handled by 0 mail.friendica-sverige.se.

I'm nor sure if this causing the messages about an invalid HTTP signature Friendica is reporting. But you should repair this nonetheless.

@petrescatraian The number of posts displayed in a channel also depends on some server side settings.

There is a total number of posts that are processed to determine if they match your channel setup and therefore are stored in the channel. Local setting: 30000 posts.

There is also a maximum age of posts. If posts are older they aren't displayed. Local setting: 72 hours.

And there are 4 or 5 settings more. 🙂

All of these settings have an impact on the amount of data stored in the database and the performance of the channel.
