Retries for DNS query? #49

Closed backbord closed 1 year ago

backbord commented 2 years ago

Hi,

I occasionally see the following message in my logs and noticed, that _query_cvd_version_http uses the retries whereas _query_cvd_version_dns does not, if I read the source correctly.

Would it be possible to add retries for the DNS query as well?

Thanks! Tim
