Hi.
I try to run this example and i received this error

Error: connection refused
[E][component:164]: Component http_request set Error flag: unspecified
[E][component:176]: Component http_request cleared Error flag

can you help me?

Thanks

I suggest debugging the http request first before moving on to esphome. I suggest trying out a tool like "bruno" for that. If you have verified that your request is correct and your bot is responding as planned, than you can continue with the yaml.

I put the same example to connect with telegram api and return this error.

with chatid: xxxxx? Again, setting up the bot (which is nessesary for this to work) is not so trivial and i'd suggest verifying that all ids are correct before continuing with the esphome

no i change the correct chat_id. is a group id but i test the conection to connect via web url and connect correctly
