Hello,
When i try to login to the Developer Forum at Home (PC or Laptop, both won’t work)
I got always the Error Unable to fetch configuration from identity provider. Please try again
I tried it on Chrome, Firefox and Edge with Firewall enabled and disabled
What should i do?
It probably is your service provider has it cached. Force a refresh.

won’t work, i reset also my internet modem 
In order to improve internet speed they cache data in a node. It is this that hasn’t been updated. Using a Hard reload in the browser will bypass that and generally updates the node but not always.

Browser haven’t work, i had reset my Internet modem complete, now it works
Here are a few steps you can try.
Clear your browser cache and cookies.
Ensure your system’s date and time settings are correct.
Try accessing the forum in an incognito or private browsing window.
Verify that your internet connection is stable.
Check if there are any browser extensions interfering with the login process.
Temporarily disable antivirus or security software to see if they are causing the issue.
Kindly reply if it works.
