My public library website, hudsonlibrary.org, is not currently accessible via Verizon 5G. Patrons have been complaining to us that they are presented with DNS_PROBE_FINISHED_NXDOMAIN errors. This started about 1 week ago. No device on any other network has shown that error. We've tried all the standard device troubleshooting but this definitely seems to be network specific.
I have triple checked with my Web host, domain host, and DNS servers, and all have the correct information. We are wondering if our site was somehow blacklisted on Verizon somehow? I've had no luck through the usual support avenues. Thank you in advance for any help!
