Hello,
I have a fresh installation of Matomo 4.11.0 running on a Apache2 server with PHP 7.4 FPM behind a reverseproxy.
I was able to add a website and see real time events but opening most of the pages of Matomo (for example Visitors > Overview) gives me the following error: (Translated with Google from German to English)
Oops… there was a problem during the request. The server may have been temporarily overloaded, or you may have requested a report with too much data. Please try again.
PHP log:

MariaDB log:

MariaDB config (relevant settings only):
max_allowed_packet = 1G
max_connections = 500
interactive_timeout = 6000
innodb_log_buffer_size = 1G
innodb_log_file_size = 4G
wait_timeout = 28800
These values are currently set very high for testing. The values from the FAQ entry also didn’t help.
When I enable the mysql general log , i can see that matomo is sending queries to the sql server but there don’t seem to be any errors or anything that indicates that somethings wrong.
PHP modules are all up and running:
apc, apcu, bcmath, calendar, Core, ctype, curl, date, dom, exif, FFI, fileinfo, filter, ftp, gd, gettext, gmp, hash, iconv, imagick, intl, json, libxml, mbstring, mcrypt, mysqli, mysqlnd, openssl, pcntl, pcre, PDO, pdo_mysql, pdo_sqlite, Phar, posix, readline, Reflection, session, shmop, SimpleXML, sockets, sodium, SPL, sqlite3, standard, sysvmsg, sysvsem, sysvshm, tokenizer, xml, xmlreader, xmlwriter, xsl, Zend OPcache, zip, zlib
I tried using the PDO\MYSQL and the MYSQLI adapter, but that changed nothing.
What should i do now?
Thank you.
