Can not connect to REST services on local network and domain-joined hosts

[azunyuuuuuuu]

When trying to call a REST service residing on the local or domain-joined network I get the following error message:

An error occurred while sending the request. The text associated with this error code could not be found.

A connection with the server could not be established

Using the command checknetisolation debug -p=S-1-15-2-2472482401-1297737560-3464812208-2778208509-1273584065-1826830168-474783446 I was able to get the following output which basically states that the capabilities for PrivateNetworkClientServer are not enabled in the .appxmanifest file:

C:\WINDOWS\system32> checknetisolation debug -p=S-1-15-2-2472482401-1297737560-3464812208-2778208509-1273584065-1826830168-474783446

OK.

Please enable this capability for us to be able to call REST services on the local network.

Hi @azunyuuuuuuu thanks for reaching out.

Nightingale should be capable of connecting to your localhost on the same machine. Have you tried turning this off in the settings menu?

[dpaulino]

Also, regarding domain-joined hosts, yes that's a known issue. I have an upcoming update to add the PrivateNetworkClientServer capability to the app manifest. I'll ping this issue again once that update is live, and I will ask you at that time to check if the issue was fixed.

This was the first thing I tried, as I suspected it is the ssl certificate. It didn't work :( But querying REST interfaces outside of the local network worked fine with this activated and deactivated.

Thank you very much. I`ll be waiting until then.

Edit:
I also found this while researching this bug: microsoft/testfx@26d82ca#diff-d9ff8be6d8da869ef024d763664ccfc5R43

This commit shows where to put the capability.

An update is coming in a few days to the preview program. Any chance you're interested in joining? The fix will be included in there.

[azunyuuuuuuu]

I have signed up for the preview program and will try it as soon as the preview is available.

[dpaulino]

The newest preview build just went live with the PrivateNetworkClientServer capability included. The version of the preview build is 3.0.2. Please let me know if that fixes your issue.

[azunyuuuuuuu]

The newest release fixes this flawlessly. Tyvm :)

[dpaulino]

Thanks for confirming!

[rasmusfjord]

So im still getting this issue :( On localhost:
An error occurred while sending the request

Have tried the SSL switch off but still getting this. Isnt this released yet?

[zippoxer]

Getting this problem as well.

[cherepets]

Hi, i'm also getting exceptions when connecting to localhost.

Have you tried the instructions here? https://github.com/jenius-apps/nightingale-rest-api-client/blob/master/docs/localhost.md

@dpaulino Hi, thanks for the suggestion, i just tried it, didn't work. Don't know why. But its okay, i can live with that. No big deal.

Thank for creating the app too, its really great to use :)

[dpaulino]

What does your localhost url look like? And just to double check, you tried turning off ssl validation in Nightingale's settings?

[delzac]

Yup, i switched off SSL validation and it still didn't work. Restart my computer too.

The url i used was http://localhost/gec/?text=Hi i also tried http://127.0.0.1/gec/?text=Hi didn't work too.

[dpaulino]

@delzac what's running on your localhost? An ASP.NET Core app?

[delzac]

Hi @dpaulino, i'm running Python 3.6 on Uvicorn with FastAPI.

Thanks for taking the time out to maintain this :)

[dpaulino]

@delzac no problem! Any chance you can set up a github repo that is configured the same way as your python project with a quick readme on how to run it on local host? I'd like to try to reproduce this.

[delzac]

@dpaulino sure thing! Would a docker image be better or do you prefer the github repo with instructions?

[dpaulino]

@delzac github repo with instructions would be best. Thanks in advance

[delzac]

@dpaulino Okay! I'll get back to you here again once its up :)

[dpaulino]

@delzac whenever you're ready, can you share your repo link using a new issue? It will be easier to track investigations on your specific scenario in a new issue

[delzac]

Hi @dpaulino I double checked and realised that the worldaround works! I so so so sorry for taking up your time.

The issue was that i didn't add the port 8000 into the url. LOL. With http://localhost:8000/ everything worked fine.

Once again, thank you for taking the time out to help and create this app. :)

[rodrigo-sobral]

Hi @dpaulino! Firstly congratz for your awesome app, it is exactly what I was needing.
However, I'm having the same issue. I've already done everything that was said here and still not working.
To give you some context, I'm running a NodeJS web server and I also tried with REST Client extension on VSCode and it worked.
The point is that I don't actually want to use it, you app is faraway more organized.

Thank you in advance! 😃

[dpaulino]

@RodrigoSobral2000 Have you tried this troubleshoot guide? https://github.com/jenius-apps/nightingale-rest-api-client/blob/master/docs/localhost.md

[rodrigo-sobral]

I'm sorry for bothering you. I actually didn't have seen that file. It worked just fine.
Thank you once again, keep up with the good work! 😃 👍🏻
