**Your software**
My Mautic version is: 4.4.1
My PHP version is: 8.0
My Database type and version is: Ver 15.1 Distrib 10.6.7-MariaDB
**Your problem**
My problem is:
We are seeing a number of connection errors in the log on connection - it is sporadic, but would like to see if there is a way to pinpoint what they are and if there is a way to correct the situation.
The site is a high traffic site.
These errors are showing in the log:
mautic.error:2022/09/13 06:39:05 [crit] 139582#139582: \*1202945 SSL\_read() failed (SSL: error:0A000126:SSL routines::unexpected eof while reading) while processing HTTP/2 connection, client: 199.999.222.999, server: 0.0.0.0:443
Steps I have tried to fix the problem:
Nothing as of yet besides writing here 🙂

Can you share more about the setup? Docker? VPS? LXC?

@joeyk - what do you think about this article: [nginx - php-fpm.sock failed (11: Resource temporarily unavailable) while connecting to upstream - Server Fault](https://serverfault.com/questions/843460/php-fpm-sock-failed-11-resource-temporarily-unavailable-while-connecting-to-u) ?

clearly not a Mautic issue, I would think - rather openSSL, maybe in conjunction with nginx and/or HTTP/2…
See e.g. [SSL\_read() failed (SSL: error:0A000126:SSL routines::unexpected eof while reading) · Issue #18866 · openssl/openssl · GitHub](https://github.com/openssl/openssl/issues/18866) where an nginx update helped.

Hi Ekke
Thanks for the reply. I already upgraded to latest nginx version a while ago.
Any thoughts on the error for
mautic.error:2022/10/03 00:25:15 [error] 572614#572614: \*666425 FastCGI sent in stderr: “PHP message: PHP Notice: SessionHandler::gc(): ps\_files\_cleanup\_dir: opendir(/var/lib/php/sessions) failed: Permissio n denied (13) in /var/www/mautic/vendor/symfony/http-foundation/Session/Storage/Handler/StrictSessionHandler.php on line 106” while reading response header from upstream, client: 199.999.99.99, server: [mymautic.com](http://mymautic.com), request: “GET /mtc.js HTTP/2.0”, upstream: “fastcgi://unix:/run/php/php8.0-fpm.sock:”, host: “[mymautic.com](http://mymautic.com)”, referrer: “[http://localhost:4200/](http://localhost:4200/)”

Looks like a read and write issue to the directory.
Check your php.ini and look for something like
`session.save_path=`
What it’s set to and check permission on that folder.

Not sure this is related to the original symptom. Quick [Google search result](https://stackoverflow.com/questions/2904862/issues-with-php-5-3-and-sessions-folder) recommends setting `session.gc_probability = 0` 🙂

Thanks @ekke , this is set to 0 already (I guess by default)…
@techbill in my php.ini this is actually commented out,
```auto
session.save_path = "/var/lib/php/sessions"
```
The files inside this directory all have permissions of www-data:www-data

May I ask, how did you solved the error? I have it also.
In my /etc/php/7.4/cli/php.ini are also:
`session.gc_probability = 0` set
and
`session.save_path = "/var/lib/php/sessions"` commented out.
Did you uncommented the “path” line? Or simply ignored the error?

I do not think I ever solved this. I have noticed that Mautic does not work that nicely with ubuntu 22.04 and php8.0

We use 18.04 cause I saw issues even with 20.04.
