@liangshiwei It seems that because the server cannot be connected, API returns an error with status 0. There is only the client side log as I originally sent. This problem happens quite often so I don't think the cause is the internet.

I only see errors about database connection

@liangshiwei
I experimented with disconnecting the database while the angular app was running and the error I received was http code 500, not http code 0.
So I think this http status code 0 error is not related to the db connection being temporarily interrupted :(

Make sense, but I didn't see any error message in logs about http code 0

@liangshiwei Thank you for your help, I think you won't be able to find http status code 0 from auth server log (netcore), api server log (netcore)
Because this is an angular client issue where the request cannot go to the server or is canceled for some reason
With my limited understanding, I can sometimes reproduce this error when the browser has an unstable internet connection (I try disconnecting the internet then operating on the angular app, I will see the status code http 0).
However, I would like to find another cause

Hi,
Okay, If so, it's a network problem; the requests are not even sent to the backend.

I will send you an example of the error. It happens quite frequently, so I don't think it's a network error. Could there be a cause on the ABP side?

As for the screenshot and content, for example, there is an error like the one below. https://bit.ly/491MYKI
I'm sure you don't know the cause, but is there any way to deal with it?

Hi,
Yes, I can see many error records. But it's not enough to find the problem.
You can try check the webserver(nginx, IIS etc.) logs, maybe you can find something.
-
0
I wish I could find something in there, but logically, the nginx web server no longer plays a role in this issue because:
- nginx webserver has served js resource to the browser
- js code (angular app) execute on browser remote call to auth server, api server and some time we got http status 0
And i double check api | auth server log on datadog link here But couldn't find anything useful

for example, the following URL is the web server log when 0error occurred, but there was no error. https://bit.ly/4fEme5i
I don't need to know the cause, but is there any way to deal with it?

You can try to check if this issue can be reproduced locally or in other environments.
