Hello @ss kk ,
Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.
I understand you are getting the following error on your azure portal
Error Message:
There was an error fetching tenants. Please reload the portal to try again. If you wish to switch tenants, you can sign in directly into a tenant by specifying the tenant domain or tenant id as part of the portal URL. For example, https://portal.azure.com/tenantdomain.com or https://portal.azure.com/tenantID
Recommended Solution:
This could be due to a firewall in your network or Anti-virus blocking the azure portal management URLs
This can be fixed by adding an exception in your AV(If any) as shown.
Steps: Open Anti-Virus app >> Click Menu >> Settings>> Add Exceptions or Exclusions >> Add Exception >> Add the URL https://management.azure.com/*
Most users reported this issue, identified that Avast anti-virus cauing this error.
