I’ve strange results while testing. I use https://internet.nl test. Everything is OK except that I receive an error. IPv4 and IPv6 Nextcloud do not match.
But if I test again an hour later or so, I get 100% Ok. And the next day again 96% with a mismatch.
I tested 2 NC instances under the same account on our server. They both act similar.
After disabling Redis the test result stays 100%with no errors.
Test results with a Wordpress site on this account are always 100%.
So there must be something going wrong in the Redis communication with Nextcloud.
Does anyone know what could be wrong?
For each application an other Redis database is used, so that can not be conflicting. The problem is also on other accounts that have different Redis ports configured.
The only thing that I could discover was a part ‘nonce’ in the output code. That part is about 33% of the pagecode for the logon screen, it seems. That code is different for IPv4 and IPv6.
The error is thrown when there is more then 10% difference between IPv4 and IPv6.
