Redirect links being blocked on Verizon?

[NelsonL17]

Noticed recently that "87gazgoab.cc.rs6.net" links in our email campaigns are being blocked by Verizon. Switching to another ISP fixes it. Is anyone else having the same issue?

Hello @NelsonL17 ,

Are you able to provide a screenshot of the error page you receive when clicking the tracked links on a Verizon ISP?

Hi @NelsonL17 ,

The "took too long to respond" error is indicating that something is blocking the redirect, or it's getting erroneously caught in some kind of filtering functionality and causing a time-out. Due to the information needed to troubleshoot this connectivity error further, I'd advise calling our general support. They'll need to go over some more technical troubleshooting elements, including:

• capturing the browser's console code errors
• a screen recording from your side of the exact behavior from clicking the link to the error page showing
• A list of browsers, browser plugins / addons / extensions, VPNs, ad/pop-up blockers, and other security software used on your device and organization's network (if applicable).
• A list of the email programs used (Gmail, Outlook, etc.)
• the exact name of the email, and if possible, forwarding it to the address provided by the support team

There may be other troubleshooting questions that phone support and the higher level technical team will ask for, but this at least gives you a head's up on what things you'll want to gather before calling in, in order to save troubleshooting time.
