In my experience, the issue commonly stems from PHP configuration settings on the production server. I’ve encountered similar problems when allow_url_fopen is disabled, which means file_get_contents cannot fetch remote URLs. Additionally, server firewalls or SSL certificate issues might block the connection to the Telegram API. I resolved a similar problem by switching to cURL for more robust error handling and verifying that the server permits outgoing HTTPS requests. Checking your server’s error logs often provides more insight into whether it’s a configuration or network-related issue.
I encountered a similar problem when moving my Telegram bot from a local environment to production. In my case, the problem was not only with PHP configuration settings but also with DNS resolution on the production server. The DNS failed to properly resolve the API address, which led to timeouts for the requests. After verifying the DNS configuration and ensuring file_get_contents was capable of handling HTTPS streams, I switched to cURL with proper error handling, which eventually resolved the issues. Checking for both PHP settings and server network configurations helped me pinpoint the source of the problem.
I experienced a similar problem when deploying my bot to a live server. In my case, the issue was due to an outdated TLS library causing SSL handshake failures when connecting to the Telegram API. I verified that my server’s PHP build had the latest OpenSSL support installed, which made a significant difference. Switching to cURL improved error handling and allowed for better debugging, enabling me to identify configuration problems more quickly. Reviewing dependencies and ensuring the server environment matches production requirements is key to resolving such issues.
