Thank you all for your answers.
I completely erased the server. I got angry and erased when the errors constantly increased during the installation.

I am thinking of re-installing NodeBB on the new server. Does anyone want to help me with this?

@gotwf said in How do I fix Nodebb installation errors:

@neron I did not bother reading all of the docs you linked but they seem dated. Official docs are what you want to grok:

There is no difference between this document and what I submitted

Hello, I installed NodeBB today.
I'm getting a few bugs, can you help with this, please.

1. Error: Cannot login to admin panel. I login as a user, but when I try to login / admin, the page loads and freezes constantly.

2.Error: I am constantly receiving an error, your connection to nodebb has been lost.

3. problem: The third problem is that even though I completed the installation without any problems during installation, SSL is not active. can this cause the problem?
