Deploy a golang websocket service but seems can only connect with browser

Troubleshooting and help
1

I try to use postman and curl connect but it seems not working.
It’s my issue or the platform block the request?
Anyone encounter such issue? Thanks in advanced!

Hello,

I’m performing the same query as you did, but I have a 400 code error.

If you have repeated connection reset, it might be related to something else like WAF or anti DDOS.
This could also be some transient failure from Cloudflare where you are. A browser usually retries these requests.

Could you try again? If this still fails, you can share your IP with the support so we can investigate this.
