Matomo dev Site cannot open Heatmap A/B Tests etc

Hello,

on our dev setup in matomo where we have 12 sites connected there is an issue while using Heatmaps/A/B-Tests/
Whenever you click on the buttons the following message pops up:

Oops… there was a problem during the request. Maybe the server had a temporary issue, or maybe you requested a report with too much data. Please try again. If this error occurs repeatedly please contact your Matomo administrator for assistance.

Same goes for the Marketplace.
I suspect it is because we limited the internet access of the Matomo server, but I’am currently unable to confirm that theory.
Can anyone point me in the right direction or the right log to find the error messages?
Or is it really just a problem with limited internet access?

kind regards
Florian

Edit:
Looks like its calling itself via curl but cannot get through fast enough:

Checking the URL ***/config/config.ini.php failed: curl_exec: Connection timed out after 2001 milliseconds. Hostname requested was: ***

Edit2:
Here is the last thing I’ve found inside the system check:

Checking the URL https://domain.de/config/config.ini.php failed: curl_exec: Connection timed out after 2001 milliseconds. Hostname requested was: domain.de
Checking the URL https://domain.de/tmp/cache/tracker/matomocache_general.php failed: curl_exec: Connection timed out after 2001 milliseconds. Hostname requested was: domain.de

It feels like there is some sort of misshap with the php_proxy so that server cannot ring itself up.

Hi @f.wischer
As this concerns Premium features, I suggest you contact directly the support team…

Hey @heurteph-ei ,

Thanks for your reply. We dont really intent on using the features. The error messages are just popping up when pressing those buttons.
And they will stay on screen even for the enduser.

I think its because of our nginx setup which is sending the curl not via https … so it gets stuck in nginx. if I manually curl the site with https everything works fine.

I will keep on digging and see if I can find anything

Hi @f.wischer. The most common solution to the message Oops... there was a problem during the request. is to setup Auto-Archiving in your Matomo by following these two steps:
a) Enabling the crontab to run the core:archive command and
b) Disabling “Archive reports when viewed from the browser” in the General Settings.
