Is anyone having trouble downloading the Yealink T58 firmware? I can download everything but this. I changed the DNS server to 18.104.22.168 and did the nslookup to downloads.3cx.com and that is all working properly but it is still now downloading. I get the error message Unable to reach 3CX Updates server. Check your internet connection and try again. 3CX is running on windows server 2016. I looked into the firmware new folder and the firmware is downloaded into the directory already. I did download the firmware from the 3cx website and updated manually. Not sure what to do now.
