unable to connect to kuma

[Johnny5AtGithub]

Hi,

I’ve just installed your addon through HACS, but I've been trying and trying to connect to my uptime kuma without any success. To be fair, at first I used my accounts' password, before I found the instructions and saw that I needed an API key. So I made that API key. Unfortunately, it still keeps saying it could not connect immediately. I played around a bit with or without http:// but nothing had any effect. Then I went to the HA logs and I found this.

It looks to me like a syntax error embedded in the source code or something. Any idea how to resolve this?

Edit:
Sorry I did not search before making the ticket, But I'm adding info now :)
--> I have tried with or without SSL checked.
--> I have tried via the nginx proxy name with a valid SSL certificate and by making a direct connection on IP and port
--> The metrics endpoint is operational. I needed to use my username with the API key I have been entering into your add-on

The API key used is set up

Additional question: I see mentions that I need to input an API key instead of my password, but on one of the other threads there is mention I need API turned off in uptime kuma, I see no generic setting to turn an entire API on or off. What is meant? sometimes the instruction is to create an API key, but API in general is supposed to be off?

The unsung HERO!!!!
It's the trailing slash!!!

So, for the record, when in the chrome browser you always show full URL enabled (right click in the URL bar) and you select your URL WITHOUT a trailing slash, control+c copies your URL WITH A SLASH!!!

So now you have a compacted problem report, checklist on what to check and a solution. This ticket may be closed.
