Problem after upgrade to 8.8.15

[JonMemere]

Hi,
We wanted to update our Zimbra which was in version 8.8.15 to 8.8.19. And we have an error like this:

2021-03-23 21:51:24,124 WARN [qtp366590980-52:https://192.168.100.100/service/extension/nginx-lookup] [] extensions - unable to find handler for extension: system failure: Extension HTTP handler not found at /nginx-lookup

Do you have an idea ?

Thank you !!

There is no such version as 8.8.19, I'm guessing you mean patch P19 for 8.8.15? Why don't you upgrade to ZCS 9?

We have our own Zimbra server. Yes, we have attempted to upgrade patch 4 to patch 19.
And we got the error mentioned above.

Zimbra version 9 is not open source right ?

Thank you.

Wrong, there are two version and those are the OSS versions provided by beezim and Xextras.
