This problem prevents me from connecting to a meeting about 50% of the time.
My router enforces DNSSEC. And half the time zoom.us isn't resolvable. Here's a snippet from my router's logs :
info: resolving zoom.us. DS IN ... info: query response was nodata ANSWER ... debug: verify: signature mismatch info: NSEC3s for the referral did not prove no DS. info: Could not establish a chain of trust to keys for zoom.us. DNSKEY IN
When I reached out to my DNS provider for help they linked me to this DNS security analyzer:
It shows that zoom.us has problems such as:
As a work around, I can turn off DNSSEC or hardcode an IP address for zoom.us in my hosts file. But I don't want to sacrifice security.
Hopefully zoom will fix their DNS records.
Thank you for this post. It would be best for you to open a ticket with our Support Team so that you can get an answer directly from our Security Team. https://support.zoom.us
One thing I noticed from the Verisign site is that any large company I search shows the same missing records as you found for zoom.us.
I looked for a way to submit a support ticket before posting here. But I couldn't find a way to do that.
My DNS provider linked that Verisign page to me when they told me the problem was coming from zoom. (I included it in case it's helpful). Perhaps the logs I posted show the problem better.
