XF 2.3 Push notification does not work

[AndreaMarucci]

My PWA is working perfectly but the push notifications doesn't work at all and also I've many error like this one in the admin

Push notification failure: cURL error 6: Could not resolve host: permanently-removed.invalid (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://permanently-removed.invalid/fcm/send/fDVj_8MeEiQ:APA91bF_3K8mtDk40nMLrcCK6jeckwTeF7FBRhqn4uMKdGSosLYflaGFp7HRZBi6cLlvr5Yba5apSXVhpbRtaxOpO89mYQSHXrB6866wRfHqO0HEQNgmiWmfNPyhoFh19T-MKMt1ZUAy

If the problem is that my server cannot communicate with the service that send the push, can someone tell me what to check and what to unlock to see these push go through?

This particular error seems to stem from cancelled push notifications. The host that XF is trying to communicate with (permanently-remove.invalid) isn't a host that exists hence the error from curl. See this bug report. The best "fix" for now is probably a cron job to remove entries like that from the database as described periodically (as I believe you have been doing) to keep the noise in the error log down.

Thanks but the problem is that the push notifications doesn't work. I can delete the entries but I'd like that the push are sent.

 

[chillibear]

Understood. That sounds like it perhaps could be two separate issues then, unless (and total speculation here) push notifications are in one queue and a failure (for example the .invalid domain) in one entry causes the queue to stop processing? Sorry I don't know the innards of how the push mechanism works, hopefully someone else can offer some insights, or if you have an active licence you could try raising a support ticket.

What surprise me is that i've asked for help in another thread and no one ever answered, that's quite annoying...

Fixed Thread 'XenForo tries to send push notifications to invalid URLs'

Nov 27, 2025

I havn't found a definitive reference for this yet, but it seems that Chrome / Chromium sometimes generates placeholder URLs starting with https://permanently-removed.invalid/fcm/send for invalid / expired push subscriptions, see https://xenforo.com/community/threads/push-notification-failure-curl-error-6.234166

XenForo currently accepts those URLs and tries to send notifications there which obviously fails and kinda floods the error log if those endpoints are utilized frequently (which happened to us yesterday).

Suggested Fix
Ignore endpoint URLs starting with...

Thanks, no hints unfortunately. Problem is not that there are errors but that the push notifications doesn't work for anyone of my members.

no hints

the link above your post appears to be the issue ?

 

[AndreaMarucci]

There are 2 issues. One is the error message that's not so important since I can delete it but the true problem is that the push notifications doesn't works at all.

 

[Digital Doctor]

the gmp, mbstring and openssl extensions enabled.

those are all installed ?

 

[AndreaMarucci]

Installed and working, I'm sure since otherwise you get an error in the admin panel

Push subscriptions are scoped to an origin/domain, so users will need to resubscribe. I'm not sure off-hand why they wouldn't be prompted again when visiting the new domain. Does the option show up under account preferences?

Push notifications are also device specific not account specific. Users can have it enabled on some devices with their accounts.

Either of these help ?

Are the permissions set ?
