Azure WebApp for Containers with random err_name_not_resolved errors

We have an Azure WebApp for Containers. This system is a SPA web where the frontend periodically checks connectivity to the site backend.

This check is a simple HTTP GET that runs every x minutes. Sometimes, which seems to be random. there is a net: err_name_not_resolved (when using chrome)

Azure reports no issues, nothing strange in our logs. so the error seems to be fully client only.

What can be the cause for this? Why would a HTTP GET fail to an Azure Website if the site is actually running?

Is it a network issue on our side, or can it be something else. What can we do to troubleshoot this?

net: err_name_not_resolved means that the domain name cannot be resolved. In general, It looks like a DNS related issue. The error may be a result of a misconfiguration on your client or router OR the website may be down.

You could try these fixes:

  1. Clear your browser cookies

  2. Flush and renew DNS. In CMD, run ipconfig /flushdns ipconfig /renew ipconfig /registerdns

  3. Change your DNS address to Google’s public DNS

  4. Check your Firewall and Security Software
  5. Use a VPN
  6. Power cycle your router
