: My site is receiving DNS errors on Google Webmaster Tools, how can I solve this? I have several irregular DNS errors on a subdomain of my site. On all my other subdomains, I have no issues

I have several irregular DNS errors on a subdomain of my site.

On all my other subdomains, I have no issues (they have the same configuration)
Just en-directo.frequence-radio.com suffers this issue.
My hoster (OVH) is telling me they don't have any problem on their side.

What do you think I can do to solve this?

Update:

The test with the domain is OK (frequence-radio.com) on DNSsy.
The test with the subdomain has some issues, but no more than my other subdomains. I copy/pasted below all the failures from the test:

Nameservers match (parent): Some nameservers returned by the parent nameserver are not returned by your nameservers. The following
differences were found: tllmxzfpqply.frequence-radio.com* (no idea
what is this last line)

All nameservers responded: Some of your nameservers did not respond. The following did not respond: tllmxzfpqply.frequence-radio.com*

All of your nameservers match: Your nameservers returned different nameserver records. At your nameservers I found: At parent
nameserver I found: tllmxzfpqply.frequence-radio.com*

All of your nameservers match: Your nameservers returned different nameserver records. At your nameservers I found: At parent
nameserver I found: tllmxzfpqply.frequence-radio.com*

SOA record: None of your nameservers returned an SOA record for your domain. This is very bad. Skipping SOA tests.*
