Bummer!

I wonder what's to be learned from your trying to get into your site from your husband's PC?

I don't know if your sig is up to date, Rita, but your Safari version is one tick behind the times...s/b 11.0.3, which I believe came along with a security update, and your iTunes isn't up to date either.

Have you checked your updates tab in the App Store lately?

I have sometimes run into issues with web sites cause by the DNS (Dynamic Name Server) blocking suspect IP address or domains and it is not always easy to determine where the issue actually originates or where an error message is coming from. In this case the solution can often be as simple as switching to a Public DNS server.

On your Mac

1. go to System Preferences > Network — click on the padlock at the bottom left of the window and enter the password for your account (assuming you have administrative privileges)
2. Once the password has been entered click on the "Advanced" button at the lower right side of the window
3. At the top of the next window click on DNS
4. There will be one or two IP addresses listed (if the listed IP addresses begin with 10, 172, or 192 you are getting your IP addresses from your local network router and most likely that in turn is coming from your ISP (Internet Service Provider).
5. Make a note of the IP address currently listed i case you want to resotre them in the future
6. Select one or the listed IP addresses and click on the minus sign (—) at the bottom of the window to remove it.
7. Repeat the process with the second IP address
8. Click on the Plus Sign (+) at the bottom of the window and a null IP address (0.0.0.0) will appear. Click the P;us Sign a second time: These addresses must now be changed to the IP address of a Public DNS Server. There are several options but probably the most commonly used are:
   • Google: 8.8.8.8 and 8.8.4.4
   • Open DNS: 208.67.222.222 and 208.67.220.220
9. The next two steps are essential to effecting the change
10. After entering the IP addresses click on OK at the bottom right of the DNS window.
11. Click on Apply at the bottom right of the Network window

On Your iPhone and/or iPad:

• Go to Settings > WiFi
• Touch the Get Info icon to the right of the WiFi Network name
• Under DNS touch Configure DNS
• Touch Manual
• Under DNS Servers touch the green Add Server button and enter the first of the IP addresses for your selected DNS server
• Repeat for the second DNS server IP address
• If there is another IP address already listed (probably beginning with 10, 172, or 192 touch the minus sign by that number to delete it.

NOTE: On iOS devices the DNS server is set on a network-by-network basis. I recommend that unless you encounter difficulties you only set your home and/or office network DNS server manually. I have occasionally encountered public WiFi networks that block access to any DNS server other than their own. Those same networks also blocked the use of VPN (Virtual Private Network) servers and Onion Routing probably in an effort to prevent their public network from being used for illicit purposes.

Thank you for that detailed information. Unfortunately, it didn't work. I used 8.8.8.8.

I thiiink you've got to use the pair, Rita... 8.8.8.8 on one line and 8.8.4.4 on a second line.

The way the pair works is there is an intermediate server that routes the DNS request to whichever address is closer on the network. The automatic setting in iOS typically resolves to only a single IP address.

When you say, it did not work, am I correct that means you still did not get through to the survey site?

One last test I can think of. I know you don't want to use your iPhone for this but it is worth a trial. On your iPhone in Settings turn WiFi off. That will force the connection to go through the cellular data link. If that does not work and you are not logging on the site with a userid or userid/password combination the problem is definitely NOT your to solve. There has to be something on their site that is blocking your access. Remember that too often the phone tech support people are chosen from a pool of individuals with little or no computer expertise. Their only expertise being the ability to read a canned script of troubleshooting steps. (I know because I used to train Tech Support "engineers" for Microsoft)

The way the pair works is there is an intermediate server that routes the DNS request to whichever address is closer on the network.

Typically the search starts at the top of the list and goes in sequence from there.
