I have a SIM800L module. Which has R14.18 firmware(supports TLS 1.0 and SSL) in it. I am having trouble to connect to http"S" servers. I can connect http servers no problem there. All this information and steps i got from datasheets, forums and YouTube videos. But i havent seen anyone connect to http"S" servers specifically.
I have no idea what I am missing if someone could rightdown the steps as a dummies guide that would be great.
Thanks in advance.
P.S: I am planing to use this with arduino iot cloud api any help would be appreciated there!
So far i tried;
Configuring the bearer and http with AT commands always getting 601,603,605 etc.
I checked the DNS and SSL cert but I'm not confident there since these are new to me
Tried to connect with TCP/IP wasn't able to connect.
Ok i figured it out i just needed to be a bit more careful that was all :)

I have a website hosted on Heroku that uses ACM for SSL certifications. This website is a small part of our entire app and I've never worked on this stuff myself. I've never used Heroku or ACM (I have read through the documentation to try to figure it out though) and I've never really done anything with SSL certifications or that side of development. So if anyone can give me any tips or point me in the right direction to fix this issue, that would be greatly appreciated!
So on the heroku website, it says that one domain failed validation. I have installed heroku-cli and ran heroku domains and made sure that the DNS target is the same. The ACM status states CDN not returning HTTP challenge.
Anyone have any ideas on what's causing this and how to fix it? I believe this website has been up for years with no issues so we'd like to keep it that way, thanks!
I was wondering if anyone has any experience with creating a mapped domain within GCP's Cloud Run with on a domain that is managed by Cloudflare.
When I do so, I end up getting a 525 (SSL Handshake Failed). With limited visibility as to what is happening on GCP's side, I can't really debug what the issue is.
Any tips or pointers would be greatly appreciated 🙏
Found my answer here, turns our Cloudflare isn't currently supported by CloudRun: https://github.com/ahmetb/cloud-run-faq#how-can-i-configure-cdn-for-cloud-run-services
I am trying to scrape the new.google.com and get some information, I have no issue locally but when I deploy to our Datacenter it fails with "connection refused" that means it is blocked.
Get https://news.google.com?ceid=en%3Agb&gl=en-gb&hl=en-gb&hs=en-gb&pz=1: dial tcp 172.217.5.206:443: connect: connection refused
Do we have any alternative of passing header and by-pass to get unblocked? or is using paid API is the only option if I have to use google for some of my testing?
Did anyone encounter and resolved it?
This is pretty common. Somebody else used the same IP address for scraping or even something worse :) so it's blocked.
You can use some proxy services. There are some with free tier so it will do the job for testing.
And before you ask... free proxy services are super slow and probably already blocked :)

I'm struggling with Netty 4.0.8 Websocket client example and SSL and I can't seem to be able to send data to the Netty SSL websocket server example. Although there have been many posts around this issue, (I went through all, I believe), and the most common suggestion is to just add an sslHandler to the beginning of the pipeline, it doesn't work. Handshake seems to be successful as it is also indicated to a relevant question here.
I remember being in the same situation with version 4.0.0, but I somehow managed to get it working. However, things (and API) changed when I upgraded to 4.0.8.
Can the Netty developers add a working Websocket SSL client example to the examples? Many people struggle with this issue and that would be useful. Maybe the solution is just too simple, but an example would clear things. Again, sorry for reposting a question that might be already there, but the relevant question has also been unanswered and my reputation is just too low to add a comment to other relevant questions :)
I seem to have found a solution to my own question. The sample code on the client uses the channel.write() method, which seems not to send the messages to the Websocket ssl server. By using the channel.writeAndFlush() instead, messages are correctly sent to the server.
