So I'm having some issues with saving DynDNS setting in FritzBox 7490 after upgrading to OS 6.83 and Fritz Support are trying to help me. They want me to generate support data by going to http://fritz.box/support.lua I can open the link fine but when I click on Generate Support Data file starts to download but never finishes. I can't repeat the process as it never works 2nd time, file download doesn't even start. If I reboot router and laptop it starts the download but never finishes and gets stuck on Downloading. Can someone try and let me know please?
