Could not connect to smtp host : 110 : Connection timed out

Errno 2: stream_socket_client(): Unable to connect to smtp-relay.brevo.com:587 (Connection timed out) at [ROOT]/includes/functions_messenger.php line 1193

the firewall is stopped for test, machine is my own VPS so no one can block anything for me, what is the problem ?

i have pinged the smtp server from the same machine as phpbb install and

PHPBB must breake something with every update.
Im using that smtp for years, never had a problem.

I am also getting a similar error to this one. Test emails are sent without any problems. However, I am getting feedback that emails for forum subscriptions are not being delivered. It gives a similar error. I think this is a bug in version 3.3.14.

[halil16]

Are we the only ones having this problem? I encounter this error a lot after the update (3.3.14).

Are we the only ones having this problem?

Your error is completely different.
Yours says it is being blocked for a security reason. The OPs is timing out on connection.

[halil16]

So is it a problem with the host? Let me contact them then.

[crywolfy]

Still waiting for someone to have an ideea for this bug, im looking at last update viewtopic.php?p=16040113#p16040113 and i see no modifications to E-Mail's

[P_I]

A more comprehensive list is available from Issues fixed in 3.3.14.

A connection timeout is more likely to be caused by or the receiving SMTP server, or something local on your server like a firewall. I can't really see how it can be caused by a update of phpBB.

I am having the same issue, which started after update as well. However, i also believe this is server related. I have my cpanel reseller looking into this as well. If we find a resolve i will post my resolve here.

Just FYI this is line 1193 in the error message

Code: Select all

$smtp->socket = @stream_socket_client($remote_socket, $errno, $errstr, 20, STREAM_CLIENT_CONNECT, $socket_context);

The only change to the messenger for phpBB 3.3.14 is here https://github.com/phpbb/phpbb/pull/6705/files
One could upload includes/functions_messenger.php from 3.3.13 package to revert it and justify if the fix is the culprit.

[durangod]

Disregard.... sorry

[durangod]

disregard, sorry

[rxu]

Thus, 3.3.14 update is not to blame, so it's up to the server configuration still. Thanks for the info.

Like i said on first post, i can get to smtp relay using PING and NMAP on the same machine, no firewall, ive tested emails daily till i did update worked fine, i did not mess with VPS for months.

Yes, it's not phpbb fault, ive tested pterodactyl and same error, don't know how to debug further since is my own VPS and no firewall no nothing...

my VPS provider has blocked 587 i switched to 2525 and works ok

Thanks

@crywolfy Why would they block 587, thats crazy stuff. Well you got it working thats most important
