Pihole DNS not working at times

Please follow the below template, it will help us to help you!

Expected Behaviour:

DNS should work and respond to queries as usual.

Actual Behaviour:

At times DNS stops working and doesn't respond.
so far i have been able to fix it by doing a telnet directly to server ip + port 53

For troubleshooting purposes, change your upstream DNS in Pi-Hole from Cloudflared to a commercial provider (Cloudflare, Quad9, DNS of your choice). See if this improves things.

that still doesn't explain why telnet to DNS ip+53 port puts all things back in action.

and looking at logs it's still serving local requests (from DNS host).

Please post what you see in the logs.
