Getting server couldn't send a response with the latest Postman client

[jaingajendra]

I have latest Postman installed in my system. and following are the version taken from the postman.

4.1.3
win / x86-32
Chrome 49.0.2623.112

Problem is All the requests(POST OR GET OR PUT) does not works sometimes. We get the following message

This seems to be like an error connecting to http://192.168.0.10:11880/positions/abc

Why this might have happened:
The server couldn't send a response:
Ensure that the backend is working properly
SSL connections are being blocked:
Fix this by importing SSL certificates in Chrome
Cookies not being sent:
Use the Postman Interceptor extension
Request timeout:
Change request timeout in Settings > General

Please let me know what could be the issue.

Regards,
Gajendra

@jaingajendra Can you check the Network tab in the DevTools window - https://blog.getpostman.com/2015/06/13/debugging-postman-requests/ ?
You'll be able to see the raw request/response payloads here.

@chisumo2016 did you find any solution? I am also facing the same problem. However, I can see this request going our and pulling response in Fiddler. Must be some Postman UI issue. I am currently using Postman v5.5.3 (latest version at this point of time)

Was facing the same issue.
Try running php artisan passport:install --force o server and then run
php artisan passport:keys --force
This will solve your problem. This happens when you copy data from local to remote database. Re-installing passport on server helps where it generates its own keys and overrides the local keys in database.
