DNS unstable

Hi all,

I don't know what the reason is, but usually I have problems with my DNS.
When I boot my Windows client I have to attempt several times to connect to my Flexshares.
Sometimes I lose connection to my web configuration and I have to switch from "Obtain DNS automatically" to "<local ip COS box>"
My COS box 7.9.1 is running in gateway mode.
Please tell me what you need to know to solve this, but don't make it to complicated please ...

Thanks for the documentation tip.
I triple checked my steps and I can't seem to figure out what is going wrong.
The link "Using Let's Encrypt Certificates for Mail and other apps" doe snot include the steps required for Serviio.
So before I start making changes to permissions and ownership, I would like some additional feedback.
I wonder if anyone (who is not a developer) ever got it working.

Please advice,

John

I usually click on "Details" & "Documentation", but that didn't give me any usable results.
https://domain.com:81 didn't work even when port 81 is opened.
The only thing that works is https://domain.com with a secure connection.

Ok thanks, the documentation made it a lot more clear.

I did it once before, but I am unable to bypass the security warning for the web configuration.
As you can see in the picture, the certificate is deployed, but I forgot how how I fixed it before.
I didn't know what services needed to be restarted, so I decided to reboot my Gateway COS box.
I tested it in another browser, but the connection remains "Not secure".

Please advice,

John

Can someone please explain to me what I need to fill in with "Other Domains" ... ?!?
I searched but I can't find any useful information.

Thanks in advance

The following commands solved it for me:

Greetings,

Thanks, but I get into trouble with the first step.
dmesg|more results in 14 pages of feedback that I don't know how to read.

Please advice,

How to copy files in emergency mode

Hi all,

I have access to a standalone COS box that I got from work, but for unknown reasons I am only able to boot it in emergency mode.
This might be basics for the average developer, but I need to copy a file from it and I have no idea where to start.
I was able to browse to the file locally and I found it, but I could use some help with copying it.
I cannot access this box with WinSCP or PuTTy, because I am unable to boot it up normally and make the changes so I could access it from my home network.
I only have FAT32 USB sticks and NTFS external USB drives.

Please advice,

John

Ps.
I would have liked to boot it up normally so I could copy some more settings from it, but I gave up on that.

Sry for the late response, but I decided to make a proper backup and start with a clean install.
Not in the mood to make all sorts of minor changes that will not fix much, because I don't have a clue how to fix problems with the iptables.

Closing this case,

John

lsmod | grep ipt
"No feedback"

Yesterday i tried booting all the kernels I have several times (back to 7.2), but with the same result.
I kept attempting to boot from the latest kernel until it finally worked. Normally I don't reboot my COS box.

I would not know how to look at log files during boot, but I told you that I have no experience with that.
Rebooting is not an option unless absolutely required, but I refuse to reboot 20 or more times for no reason.
