Testing newsletter & Url not verified

[Alina]

I created a newsletter with 8 news and buttons "read more" under each of them. The problem is that after clicking button, I get a white page with a note "Url not verified". Funny thing that 7 buttons doesn't work. 1 button works and sends me on the right page. Although, urls are correct in the newsletter. But when I click those seven buttons and look at the url where it sends me then it's like:

https://mysite.com/?nltr=NDI7MTM7(and lots of letters and numbers)

I saw a similar topic here: https://www.thenewsletterplugin.com/forums/topic/url-not-verified-from-links-in-emails. But I don't really understand Sendgrid etc.

Also in the test message, I see that online view doesn't work and it's says that it wasn't send?

Anyway, it's not the first newsletter which I'm sending and previous newsletters had no such error. No problem with buttons and links.

Hi, to undertsand the problem I need to see a not working url and debugging it. Almost surely there is a server side redirect not correctly working or a caching plugin (we had issues with wp-rocket) which changes the url format bracking the signature.
