Sometimes no internet and status „retried“

Help
1

Hi,

with my new provider (for 1,5 years now) sometimes my devices do not connect to the internet, browsing on phones stucks and also many other devices seem to have this problem. After 1-2 minutes everything works fine again.
With the last update I noticed the status „retried“ in my webinterface and every time these connection problems appear, a status „retried“ is written. I am using only my 2 providers DNS servers.

For testing I switched to Cloudflare DNS just now and deleted both providers DNS entries from config. If this works without problems, is there a problem with my providers DNS servers or are there other reasons possible?

btw: many thanks for several years of Pi-Hole without any big problems (before switching to my new provider :smirk:)

regards, Frank

The most likely problem is with the DNS servers. If you change upstream servers and the problem is resolved, you have isolated the cause.

Hi again,

I have switched to Cloudflare DNS for 3 days now. The time for a successful forwarding to Cloudflare takes not so long most of the time, but the problem stays the same:

Any ideas? If you need a debug token pleaase let me know!

Try do a tracerouter when have the issue:

pi@ph5:~ $ traceroute -n 1.1.1.1
traceroute to 1.1.1.1 (1.1.1.1), 30 hops max, 60 byte packets

If it cuts short, thats where your problem lies.
For Windows you have below similar command:

C:\>tracert -d 1.1.1.1

Tracing route to 1.1.1.1 over a maximum of 30 hops

After using Cloudflare DNS without big problems I switched back to my providers DNS after some days to compare both settings.
There is no problem with internet anymore but with both settings the retried status still appears 80-100 times a day. The time between retried and forwarded is mostly 0 sec. now.

Are there any changes made in the recent update which affects this behaviour?
