Sentinel: Update Master Database error

[bravo14]

I'm on desktop. I'm running the latest version of Sentinel. Yesterday and today I tried to update the master data base and gives a error. I went to laptop and it updated no issue there. I took a screen shot on the desktop of the error.

Many threads discussing this. I tried it just now on VZ, worked fine. Who is your ISP? Some block FTP

SD card issues? Try replacing your SD card and see what happens. Many times, the SD card is the root of such issues. Good Luck!

No sd card was inserted. Tues or Wed I do the weekly update on the data base.

I doubt it has anything to do with your scanner. Whomever you use for DNS might be blocking access to it though. From a Windows Prompt:

nslookup -q=a ftp.homepatrol.com

See if returns any result

A lookup for me resolves ftp.homepatrol.com to 172.108.246.101

So temporarily you could edit c:\windows\system32\drivers\etc\hosts and add:

172.108.246.101 ftp.homepatrol.com

Open command prompt on your PC and type

tracert ftp.homepatrol.com

it should stop at an IP address ending at .98 and the target is .101

Odd it worked last week. I'm going to uninstall sentinel and reinstall it see what happens.

Do the tracert 1st
It maybe your ISP DNS Server

I'd be surprised if it's a sentinel issue. Sentinel is trying to get your system to do a DNS lookup on ftp.homepatrol.com, and that is failing. I'm leaning toward it being something else, DNS or Windows Resolver related. Doing a DNS lookup from the prompt would tell you.

nslookup -q=a ftp.homepatrol.com

Either it returns the address ending in .101 or it doesn't. And I'm guessing it won't.

Tracert is not necessarily going to end with the .101 IP. it doesn't for me. I can FTP it though. All depends upon the firewall on both ends and the OS and whether traceroute is using TCP or UDP.

From command prompt:

ftp ftp.homepatrol.com

C:\Users\rodnitm>ftp ftp.homepatrol.com
Connected to ftp.homepatrol.com.
220 Microsoft FTP Service
200 OPTS UTF8 command successful - UTF8 encoding now ON.

I ran it and as I stated it ended at .98 which is related to .101
Point was you can see if it stops at the ISP level or Destination.

Understood. But if it doesn't stop at the destination, it doesn't mean the destination is not responding. It means there are firewall rules in place to prevent a traceroute all the way through to the destination. That's why I posted the FTP info to show that the server itself is responding on its FTP port.

2-3 weeks ago I cloned a ssd drive (win10) to the m.2(win10) and I wonder if that had to do with something with it? I plugged the sdd back in and took out the m.2 and went to sentinel and it updated to the 8/17/25.

I'm thinking this too. Turn off and then on your router & ISP modem. This would reset your DNS lookup.

I only update the Sentinel DB infrequently. Over the past month, I too ran into the same type of error. I hadn't changed a thing. I kept re-trying every other day or so and then it worked. I just figured the site was "down for maintenance" or similar.

 

[daugherh]

One other thing you can try on Windows on your PC is open a command prompt window and type in "ipconfig /flushdns" without the quotes to help clear any bad DNS entries you may have on your PC. Then try the update again.

 

[dmfalk]

Some DNS servers go flaky from time to time, especially when they're updating their own databases. Cloudflare's 1⁴ (1.1.1.1) goes through this every so often (average, about once a week), so when it does, the DNS cache in your system needs to be reset. The best way is to disconnect and reconnect your entire ISP connection, as that'll clear the cache, after being reassigned a dynamic IP address. So, next time you have trouble connecting to any site, this is one thing to check for. (If it persists after a restart, the problem is definitely the site, not your connection.)

Very obviously a DNS issue as mtindor has indicated. Most home users get their DNS info from their router and the router by default gets its DNS info from the ISP. You can easily determine where the fault list using NSLookup.

ipconfig /all will tell you where your computer gets its DNS info, usually your router.

nslookup ftp.homepatrol.com returns whatever the router thinks the IP address is. If it doesn't have an answer, it forwards the query to the ISP DNS server unless the router has been configured to query some other DNS server.

nslookup ftp.homepatrol.com "IP address of any DNS server" will return the answer from any DNS server you query. For instance.

nslookup ftp.homepatrol.com 8.8.8.8 will query the Google public DNS server.

If you do a whois on the domain homepatrol.com, you can even determine Uniden's DNS servers and query them directly.
