[solved] remoting/soap without SSL? on dev VM.

Sers!
I am trying to use the remoting client on a local VM (ubuntu 20) with fictional domains (domain.ngfr). This means I can not get a SSL certificate. Sadly, SOAP displays me an error ("SOAP Error: Could not connect to host") when I try to use the example/login.php
The soap_config.php should be set up correctly (it works on my live system) but neither https nor http (shows a bad gateway error) locations work. Not with localhost (didn't work at all, not even on live.), not with 127.0.0.1, not with domain.ngfr (domain works on live).

I checked phpinfo(), SOAP is enabled.
Username fits, Password fits as well; I changed it thrice now, just to make sure.

So will I need to go through the hustle of creating a self signed cert (any simple tutorial links plz?) or is there a workaround for this?
Thanks!

Edit: I tried setting "exceptions => 0" in login.php, here's the echo:

Code:

Logged successfull. Session ID:SoapFault exception: [HTTP] Could not connect to host in /var/www/clients/client2/web6/web/import/login.php:16 Stack trace: #0 [internal function]: SoapClient->__doRequest() #1 /var/www/clients/client2/web6/web/import/login.php(16): SoapClient->__call() #2 {main}
Logging out: Logged out.

 

Thanks!

Here, I rewrote your Documentation site:
https://floh.zone/uplds/ispc/API-docs-nmnd/index.php

Why? Because I was annoyed of it being eyeburn-white - and my "dark reader" plugin not being able to work with it, so I wrote a quick php page. It most likely can be immensely optimized but we don't do that here.

Downside: This makes it not really usable - locally, as it needs to be hosted on a phpable machine.
But on the Upside!
A) It's more beautiful - no more oldschool frameset shenanigans (who does that!?)!
A2)lso more beautiful: Dark page. No more eyes-burning-out when you switch over from p*hub in the middle of the night.
and B) more useful for those that document.
C) easier to edit because I used external CSS (see "./css/style.css" and "./css/articlestyle.css")

Function is:
There is an "articles" directory, in which I put all of the original .html files from the "API-docs" directory. I made PHP glob through that directory and display all the files as navigation links.
When clicked, a get value is submitted and the page content is displayed/included into the "content" container.
This means: Every new "article".html that is dropped into the "articles" directory will automatically be listed and clickable.

There's one more tiny issue: Somebody used inline CSS in a few lines of those article files. Bad no no! >:O
And I won't be the one cleaning THAT up.
But I could not see any issues in my short little test. So you just remove those when you find issues.

Another change: the "Home" button on the left got turned into an ISPC-Logo. Dunno how that happened, bug maybe? But I won't question a working system.

This is the DL link: https://floh.zone/uplds/ispc/API-docs-nmnd.zip

I hope this is useful to you in any way. If it is not, don't worry, at least it is for me, as my eyes will be spared. And to update, I simply need to replace the current article files. :3

 

This helped me.

I just stumbled upon this thread: ISPconfig 3.1.7 certbot Could not verify domain xxx.xxx.fr, so excluding it from letse
Which maybe could have been a solution as well.
