Sentinel: Update Master Database failed

[nc6a]

Trying to update the master datebase and I get a window stating;

Updating full database failed
Operation is canceled
The remote name could not be resolved "ftp.homepatrol.com"

Any help would be appreciated.
Thanks, Don

Did it work before?
Who is your ISP? Some will block FTP access.
Some had success flushing the computer DNS cache.

It's always worked until now. ISP is Charter

I don't think they block FTP.
Try clearing the DNS cache by going to the cmd prompt then enter in ipconfig /flushdns

Just tried using my phone as a hotspot and it works??
So all is well, no idea whats the problem is with ISP.
Thanks for the help.

Any inadvertent changes to your firewall ?

Haven't changed a thing. Weird it works fine using the phone as a hotspot.

Not really. It just means something on your computer or network is causing it.

If you want to find out the root cause, do this, one at a time. It may help us to advise anyone else that runs into this
1. Clear the computer DNS cache.
2. If you're still getting the error then temporarily disable any firewalls/internet security programs running, one at a time.
3. If you're still getting the error then reboot the computer.
4. If you're still getting the error then reboot the router.

Are you getting an error when you tried to update the Master Database?
I see 06/04/2023

 

[enosjones]

Didn't when I tried yesterday

 

[enosjones]

I hadn't updated for a month, when I did yesterday it only updated to 5/28

Mine did not show an update yesterday at about 10pm. Just updated at 11pm tonight and it worked.

The remote name could not be resolved "ftp.homepatrol.com"

DNS issue. Best way to troubleshoot this is using the Windows nslookup command.

Open a Windows command window and then

nslookup ftp.homepatrol.com (Not only will that give you the IP address of ftp.homepatrol.com or "could not be resolved" error message, it will tell you which DNS server responded to your query. Almost certainly your home router that connects you to your ISP.)

Find out one of the addresses of your ISP's DNS servers. Now try nslookup ftp.homepatrol.com <ISP's DNS Server's IP address>
If you still get the "could not be resolved" error message, the problem lies upstream of your home network.

Finally nslookup ftp.homepatrol.com 8.8.8.8 will tell you if the problem lies upstream of your ISP.
