Steps to replicate it:

  1. On my instance I click on the Talk icon
  2. Instead opening Talk, I’m faced with a error page about some internal error
  3. Cannot access `Talk´ app

So, apparently it was all my fault. I edited the redis.conf to use UNIX sockets, but apparently I didn’t saved the file properly before restarting Redis.

After re-editing the redis.conf file, saving it properly and restarting the Redis server, all issues went away.

It only came to my mind to check that small detail after posting the question.

All fixed now. Sorry for the noise.
