I checked my running status with hollaex status command, and it looks everything is fine.
What I doubt is cloudflare.
I have set up cloudflare to send all traffic to https. Accordingly, I changed the api and main address to https in the config_map file and ran the hollaex --web restart command.
Could these parts be a problem?
I see. Enabling the Cloudflare CDN for the API domain could cause a connection failure, depends on your settings.
I want to ask you to retry it after disabling the CF CDN for the API. CDN for the web would be okay.
Also, to discover the exact issue, please try to log in on the exchange web while the browser developer console (something like the screenshot below) is open. The console will tell you more detailed information about the problem you are having.
