Are Spectrum DNS Servers Having Resolve Errors?
I'm having the same problem as this user: https://community.spectrum.net/discussion/169554/spectrum-support-says-spectrum-doesnt-use-dns
A quick scan of the forum shows that others are having similar issues:
For about 2 months now, I've had consistent DNS resolve errors when attempting to access webpages. This happens across multiple Win10 devices and multiple browsers on those devices. I'm using only Win10 security, no additional blockers, and no VPNs. I receive errors like "Website Cannot Be Reached" followed by "DNS_PROBE_FINISHED_NXDOMAIN" or "DNS_PROBE_POSSIBLE". I have to hit the browser refresh button 3 to 4 times before it'll finally connect to the website. Subsequently, other pages on that website will often not load completely.
Yes, I've done all the standard resetting, power cycling, etc. of all devices, including initiating a "Reset" of my modem from the Spectrum website. Spectrum rep said everything was "green" on my router.
I finally changed the DNS servers from "Obtain DNS server address automatically" to Google's DNS servers (188.8.131.52 and 184.108.40.206) using this guide: https://www.howtogeek.com/167533/the-ultimate-guide-to-changing-your-dns-server/.
The problem resolved instantly. When I switched back to "Obtain...automatically", the problem didn't reappear, even after flushing the DNS cache.
So there's either a problem with Spectrum's DNS servers or something is getting hung up in the DNS settings on one's router or in Win10. I recommend Spectrum techs check their DNS servers and I recommend users cycle the DNS servers on either their routers or their clients in order to try to resolve the problem.
