Has anyone had any luck successfully configuring DuckDNS and Let’s Encrypt using a FIOS Quantum router? I’ve tried multiple port forwarding settings on my FIOS router but have not successfully gotten DuckDNS and Let’s Encrypt to work.
Same as @Vlad’s experience here. Before moving everything to Ubiquiti gear and ditching their “quantum gateway” I had no problems with port forwarding and Duck DNS.
