Temporary failure in name resolution

Hi, team!

Yesterday and today I get letters to mail:

Debian 10.11 Hestia:v1.5.11 Auto update.

What went wrong?
This is due to automatic update?

DNS stopped working on your server, check your dns configuration. The server also may be slow, due to missing lookups.

Hey,ScIT
Thanks for the answer, I will check the configuration.

I consult where this DNS configuration is reviewed, since I have the same problem, if you could provide more details I would greatly appreciate it.

/etc/resolv.conf

Check if ping google.com works or otherwise check your network configuration

Hi! Today I received mistakes again
Check if ping google.com works - WORKS
/etc/resolv.conf - There is no file
Found a file - etc/resoivconf/run/resolv.conf:
nameserver (ip-contabo.com ,my vps )
nameserver (ip-contabo.com ,my vps )
search invalid

I need to create a file separately in /etc/ ?

[AlexMKTD]

Those are the emails that I am receiving, I have already pinged google from my server and it is responding as seen in the screenshot

I appreciate more instructions to solve this problem.

@AlexMKTD what happens when you run on your server:

nslookup vps.alexhurtadomktd.com

You can also add
127.0.0.1 hostname

to your /etc/hosts file

[eris]

If ping google.com is working it should be fine what happens when you run:

nslookup hostname.com

[AlexMKTD]

This is the response I get on my server.

@eris

hostname.com

Server:         213.136.95.10
Address:        213.136.95.10#53

Non-authoritative answer:
Name:   hostname.com
Address: 144.91.73.12

Maybe a problem on the side contabo ?
