Cannot View Local Websites

Hi guys

I am pulling my hair out here. we have 2 offices in different locations. The “main office” (office A) has a squid proxy server in the office the “second office” (office B) has none. I have recently experienced some issues with squid and have disabled squid at the main office. Internet now fine. Now the office B cannot access any local websites that is hosted at the Main office. I can ping the address which are .local addresses at the end, I can traceroute but if I try and browse via a browser it just loads and says “site cant be reached”.

I enabled proxy again then it started to work office B can access office A websites. But I cannot leave squid on as office A experiences internet issues with squid on. the two offices are linked via IPIP tunnels. static routes are set up, they can ping each other, ssh between, access file shares, RDP all services besides the websites that are working.

is there anyone that can assist me here

Are the “local websites” accessible from WAN?
Do you try to open them with their public fqdn?
If so, look for hairpin NAT.

nope they should not be accessible to outside. they are private sites so they are sitting on the private subnet.
