Website Blocked

[GASKIM]

Web site https://www.jamtec.co.uk  is no longer accessible via any of my devices connecting to my home VM Router.  I can connect through my mobile phone network and I can connect through a work laptop through my company's VPN.

This site has been accessible in the past but is no longer accessible with an error "The connection for this site is not secure" suggesting that there is a certificate problem (which I believe to be a red-herring) as other people outside of my home can access the site without issue.

I have rebooted the router several times.  I have accessed the settings of the router.  I have switched off-on-off the web safe settings.  I have added the address to the "accepted" list of web addresses on the router.  I have submitted the web address to VM themselves to add to the "accepted" list of addresses.

This web address is important to me as it also supports me email associated with this company and I am unable to send/receive emails from this JAMTEC service.  I can still send/receive my hotmail email without issue.  I can also access other websites without issue.

The VM services stopped last night and then came back again - coincidence, I don't know.

Any advice appreciated - thanks

The DNS IP entries for www.jamtec.co.uk. have been removed. 

Connection to this site is going to vanish from all ISPs very soon.

Below we try a DNS lookup first with the Virgin Media DNS and then via Google Public DNS, both fail.

C:\Users\Philip>nslookup jamtec.co.uk
Server: cache1.service.virginmedia.net
Address: 194.168.4.100

Name: jamtec.co.uk    ( NO IP Returned )

C:\Users\Philip>nslookup jamtec.co.uk 8.8.8.8
Server: dns.google
Address: 8.8.8.8

Name: jamtec.co.uk   ( NO IP Returned )

Hi @GASKIM 

Are you sure the site is up and running?

Pick up the phone to JAMTEC and let them know what you are seeing.

There may have been a recent update to the DNS records that has gone wrong.

Hopefully it is not the first signs of a company that has closed the doors.

The site is working normally for me via a BT connection at the moment. From the home page ..

The IP has been re-added to the Authoritative DNS & has propagated correctly.

Access to the website has been restored.

Looks like they did a DNS update on 25 April - 

jamtec.co.uk. 86400 IN SOA ns1.uk2.fcomet.com. root.uk2.fcomet.com. 2023042504 3600 1800 1209600 86400

Are you still having issues connecting to the site?
