ISPCONFig serv is now taking a long time to load the interface after a network change connecting ISPConfig server direct to ISP's fiber (via unifi DMP). It previously had an extra step through the ISP's router/firewall. The intention on cutting out the ISP's router was to make things faster. Now the ISPCONFIG server interface is taking several minutes to load and emails are taking much longer to send and receive. Anyone have any ideas?
Resolved. Was due to firewall error in Unifi DMP that resulted in a DNS problem possibly also contributing to an earlier problem with Spamhaus. The new zone-based firewall in Unifi DMP is easier to set up than the previous traffic rules but still not proof against errors.
