For completeness, the error logged in server.log is:
2021-04-07T13:28:45.075+02:00 ERROR [EventProcessorExecutionJob] Event processor <5e4aa8abe1b7e23519b6ee63> failed to execute: parameters=AggregationEventProcessorParameters{type=aggregation-v1, timerange=AbsoluteRange{type=absolute, from=2020-02-18T07:43:27.781Z, to=2020-02-18T07:48:27.780Z}, streams=, batchSize=500} (retry in 5000 ms)

Hello,
I see your using HTTPS. The errors you see on the GUI might be from your Certificates and/or the Graylog server.conf file. I cant tell because the lack of information of your envirnoment.
If you could explain in greater detail how you set up Graylog Server, what configurations you made, etc… that would be very helpfull to troubleshoot your issue.
Yes, we’re running through apache2, configured like this:
<VirtualHost *:443>
ServerName gl.FQDN.com
DocumentRoot /var/www/html
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Location />
RequestHeader set X-Graylog-Server-URL "https://gl.FQDN.com/"
ProxyPass http://127.0.0.1:9000/
ProxyPassReverse http://127.0.0.1:9000/

</VirtualHost>
The ssl certificate is valid, and since the whole of graylog works perfectly, I didn’t think of including the apache config. Sorry.
It is just this paticular notification under “Alerts” that is causing the server.log errors, and that I cannot delete. I created and deleted a new test notification, just to make sure that there is no bigger global issue.
It seems some kind of corruption exists with this particular notification, and as I no longer need it, simply getting rid of i would be fine. But how…?
In the past we tried out the 3.2 version, and did not like it. So we changed back to 3.1. But I guess that upgraded something (incompatible with 3.1) in the database.
I now upgraded via 3.2 to 3.3, and: we like the newer version, the problem above is gone, and the reason why we reverted to 3.1 is also solved. (easy one-click reverse-sort of the search results)
