Can anyone please help in finding why IPB is unable to connect to Redis server?

Constants.php is updated with correct details and still receiving these errors.

Redis ping pong working

 

Background Info: Few weeks back sever restarted gracefully and corrupted the disk caching template and halted whole site.

After a while disabled the template caching by @DawPi advise and site came back online.

But Redis is still not communicating with IPB - I assumed due to server restart, perhaps. 

Appreciate any help to get redis online, please.

Thanks in advance.

 

Have you verified the redis details are still correct with your host?

Yes I have copy paste the same pw that has been used in older constant.php.

Appreciate your help.

Maybe you can advise how to reset redis pw thru SSH, so I can try that.

As until today after 3 week disk caching template throwing same error.

I have the same exact issue with php 7.4.x. Debian 10. I turned to socket and still it has an issue. I moved to memcache for time being, 

@AlexJ and what did IPB support responded?

I would recommend trying a standalone script that connects to redis, stores a value, then retrieves and displays it just to make sure everything is in fact working correctly.
