Since our website company changed the IP address of our Wordpress site we cannot access it. only happens in our office. We get a message to check our firewall but I have never changed anything? If I leave our office it works? Anyone know where i should start looking?

My first guess is a DNS issue of some type.

Can you access it at your office by using the IP address?

…it’s always DNS!

Are you able to access it via your phone not using your work WiFi?

This is almost certainly DNS. I would check your A records for an entry pointing to the old IP address?

This may be a long shot, but can you check what other sites are on that web host server. Some firewalls are aggressive and don’t just block the sites, but also the public IP address. If for example adult sites are hosted with your webhost provider, it could be blacklisted by your firewall. Your site is just collateral damage.

What error message do you get? It will likely give you clues.

What is your internal domain FQDN? What is the website FQDN? Are they using the same domain?

Agree with the initial assessment to check DNS.

Run the commands:
nslookup yourwebsite.com
nslookup yourwebsite.com 8.8.8.8

This will perform two DNS lookups, one against what should be your internal DNS servers (most likely Domain Controllers), and the second does it against Google public DNS.

Are they the same? Is the internal result the site’s old IP address? If so, you need to update your website’s internal DNS record to reflect the site’s new IP address. Then things will start working.
