I got this error when trying to use Telegram trigger node: “Telegram Trigger: Bad Request: bad webhook: An HTTPS URL must be provided for webhook”
I also used this WEBHOOK_URL=http://<local_ip_address>:5678/ in the docker-compose file
After a while, I thought the --tunnel is disabled by somethings, so self-hosted n8n didn’t have a webhook to set for TelegramBot
Hi @Le_nAm, welcome to the community!
I am sorry you’re having trouble. From looking into this it seems n8n version 1.1.1. doesn’t set the tunnel URLs correctly. This has been fixed since here, so perhaps you simply want to use a later version of n8n instead? Just tested this with 1.4.0 and could use the Telegram trigger through the tunnel URL just fine:
Keep however in mind that the tunnel URL is only temporary and there are no uptime guarantees, and as such it’s only meant for testing and development purposes. If you want to use your workflow in production you might want to consider registering a permanent domain controlled by yourself instead.
Hi Jam, tks for your reply. I have configured the tunnel, and it worked well. Just my mistake because I didn’t see the change logs about the command “n8n start --tunnel” to “start --tunnel”
Glad to hear, thanks for confirming!
This still needs updating in our documentation, so is easy to miss currently. We’ll hopefully get an updated version out soon
