Failed to communicate with URL

Hey @raoof 👋

My warmest welcome to the community! I’m sorry to hear this has been giving you some trouble, bu let’s dig deeper together.

That’s quite odd! I’ve just tried sending a random “challenge” to your URL via Postman, and was also not able to get a response, although I’m able to open the link directly:

I would recommend checking your back-end setup. Perhaps the route here isn’t quite right?

Thanks @AlexSavchuk, but I can connect with insomnia(another http client like postman)

I created this dns record 3 days ago, is it related? I know server http bindings are correct. can you try to do a dnslookup from your side

@AlexSavchuk I tried with postman just like you,

@raoof

Is there a chance this is set up for a local environment only? I’ve just tried Insomnia as well and that didn’t work for me either:

I’m sorry I wasn’t able to point you in the right direction just yet. Are you using a self-signed SSL for this URL by any chance?

-Alex

@AlexSavchuk thanks for finding the issue, no it’s not self signed, I’m using Let’s Encrypt which I think is a trusted issuer, but I could get same error like you when I checked the ssl validation(it was turned of). let me see if I can issue another one. thank you very much

for those who have same issue, the issue was related not to find the CA in cert, the fix is to use Let’s encrypt fullchain.pem instead of cert.pem

@raoof

Amazing, I’m glad you were able to find a solution here 🙂 Thanks for sharing with the rest of the community as well!
