Could not handle http requests with EC20

Hi, I am currently using EC20 as LTE module to connect my embedded system to the internet.
I have followed some online resources to set up the ppp0 network, and I am able to ping the internet.
For example, it works well when I ping or ping google. com. However, it seems that it could not handle http request since I have tried to reach websites such as http:/ /wtfismyip. com/text with cURL.

$ curl -v http:/ /wtfismyip. com/text

  • Trying…
  • Trying 2a01:4f9:4b:4c8f::2…
  • Immediate connect fail for 2a01:4f9:4b:4c8f::2: Network is unreachable
  • Connected to ( port 80 (#0)

GET /text HTTP/1.1
User-Agent: curl/7.58.0
Accept: /

And no response is received.

I am unable to connect to my openVPN network as well. I wonder whether there is extra setting to enable the module to receive high level response. Thank you.

Dear Philschan319,
Thanks for your inquiry in Quectel forum.
For yous issue, could you introduce how you test HTTP request ? Just as you have said that the module already can access the internet via PPP0, you can access the URL via browser to have a try. Normally, it have no other needed setting. Thanks!
