It's been more than 24 hours and still blacklisted. On another note, I can't access my admin extention.101 from a different ip address. Oh well, looks like I'm dead in the water as far as making configuration changes.
what @bitn2 said is true, it depends on where you install the 3cx server, if it is free hosting, wait until the blacklist opens, try using another connection such as a 4G/5G connection for comparison, if hosted on premises, try using another local ip. don't give up!
Hello all. It's been a good run for the past years, but I'm just not being successful. I never really got my system configured after upgrading to v20. Perhaps letting the subscription expire and starting fresh will work better for me.
