Thanks for your inquiry in Quectel forum.
About your quetsion, could you help to double check whether your URL is normal or not ? Or whether you use the HTTPS not HTTP URL ? The following is the AT sequence of HTTP for your reference, please double chek it.
Thanks for your reply.
I tried the exact steps as you mentioned above.
Initially it worked (not completely)…it didn’t worked completely is because,it at least got connected after AT+QHTTPPOST,but after posting the data it replied me http response failed.
But now again it is failing with the same response saying http dns error.
So can you please tell me whats wrong I’m doing ?because it got connected initially.
Just as i have said to you, please double check whether the URL you used is normal or not, you can try to open it with a browser. Or you can change another URL to have a try again. Thanks!
