Redis on one more sites

Hello everyone, Today I setup a second website in my VPS server , everything runs good 'till I install Redis. After that, my first domain (domain1) redirecting to the new one (domain2). I searched around and found a similar topic back to 2015

I added the line define( ‘WP_CACHE_KEY_SALT’, ‘’ );

to both of my wp-config’s , restart nginx etc but nothing changed.

Any idea ?

**>> EDIT: I removed redis from both of websites -> Reload Stack -> Reinstall redis for domain1 - and domain2 -> Reload Stack again -> Seems to working 'till now. I will update if anything change. **

Thank you. Keep up the good work (Y)
