Timeout while connecting to the selected mirror opnsense [Resolved]

[BatMen]

Hello to all in this community - i' new her

I want to share my solution from "Timeout while connecting to the selected mirror opnsense" in 20.1.x.

A few week ago i updated from last 19.x to 20.1.2. Worked like charm. 2 day ago i wanted to upgrade to 20.1.3 from the WebGUI and i run into Timeout ..., i could get the Security and Healthcheck, from web interface i did DNS Lookup, ping and traceroute for example to ip4.google.com - it worked. Update form console from 20.1.2 to 20.1.3 worked.
At this point i first didn't realised that tracerroute,ping and update from console took a litle longer to start (DNS resolve was slow).

My mistake was (i don't know why) - DNS Lookup took to long (it worked but with this output)

DNS Lookup from WebGUI:

Code: [Select]

Response
Type Address
CNAME ipv4.l.google.com.
A 172.217.23.174
Resolution time per server
Server Query time
127.0.0.1 No response
192.168.100.1 19 msec

Resolved: with System/Settings/General - "Do not use the local DNS service as a nameserver for this system marked" check it out  - this removed the 127.0.0.1 from
 

Code: [Select]

root@XXXX:~ # more /etc/resolv.conf
domain XXXX.local
nameserver 127.0.0.1
nameserver 192.168.100.1

wich showed in DNS Lookup took to long "No responce".

I hope this helps other people around :-)

Have a good time all

Some nice tips - use the Diagnostics from interface if you think you have the same problem or use the shell

Code: [Select]

Ping from shell:

root@XXXX:~ # ping -s 1500 212.32.245.132

Thanks for this fix. I was having the same problem after an upgrade.

For me, "Do not use the local DNS service as a nameserver for this system" didn't fix the problem.
However, marking "Prefer to use IPv4 even if IPv6 is available" on the same Systems-Settings-General page, did.
