Install Portainer - DNS Error

I thought I was being careful but evidently not careful enough.

1. Was working in portainer to delete anything relative to Plex (containers, images etc.) so I could do a new Plex container
2. Something went haywire
3. Long story short - I uninstalled Portainer completely in OMV-Extras>Docker>Portainer
4. Now upon reinstalling Portainer I get the dialog box in Por01.jpg
5. I have DNS set up as shown in Por02.jpg

Need the forums help badly. How can I get it reinstalled successfully?

Man, has this thing ever spiraled out of control on me today. 1/2 hour job now into 5 hours. Had it all working fairly decently, with a few tweaks needed, and then screwed it all up. That'll teach me to mess with things. Yeesh!

Not Yet. In what capacity should I use it? Just pinged my DNS 8.8.8.8 and returned 4 packets.

Just used omv-firstaid but did the docker rather than the enp37s0. That left me with a docker0 interface and no enp37s0. So then I added the enp37s0 back in. Now I will see if that worked.

Should I delete the docker0 interface?

I've tried 1.1.1.1, my router ip, 8.8.8.8, everything that I can think of (but then again, I'm not an expert OMV person). Nothing is working. Does this mean I have to reinstall OMV5? Is there something wrong inside of Docker or Portainer? I had been using portainer and a plex container just fine for two days until I tried to delete some old linuxserver/plex images and some old plex containers (leaving the portainer container only) so I could just do a new plex container. Then every time I created a new container it would FAIL and say it could not locate a plex image. After that, everything is downhill.

macom, thanks so much for replying. I was hoping I would see a response(s) from the forum this morning. Last night I was using another thread to try and solve things -BUT- like your post #7 I don't know where to type in the commands you requested outputs on. Please tell me how to do that. Also, I have, one at a time tried, about 4 DNS server including the router IP, all to no avail. I'm going to make a coffee and then return to this to get busy on outputs if there is a reply on where to type the commands. I sure hope I (we) can solve this without reinstalling OMV5. Thanks.

Okay. Got it. Will be using Putty on Win10Pro since I'm familiar with that.

Okay, so here's my first input. Am I doing it correctly? Seems like an unsatisfactory return.

Bear with me here . . . still learning . . .

1. Through a short trial run I now know how to institute the </>
2. Is it safe/advised to publicly display my server IP ????
3. How do I get to a new prompt in putty after the long return of your last requested command so I can ping 8.8.8.8? There are a ton of lines posted after using the last command.

He copy and pasted it rather than typing it.. and if you look at that - , it's not right. I've seen this happen before.. (look at the difference below.. 2nd one I typed)

I will [type] in as soon as I can determine how to get at a prompt from the last code return

Is this what is wanted?

Ok for those two,

now we know that you have internet connection and that systemd-resolved is enabled and running

Got it. Worked.

Question - Is it safe to publicly display my IP address? Reason I'm asking is I see a discrepancy in IP's when running command [cat /etc/resolv.conf]
