Server side events (SSE) is interrupted in approx 100s

Hello, I am new in ClaudFlare and faced the problem.

I have the notification service that uses SSE/MercureHub. After migration to ClaudFlare DNS we have faced connection interrupting. The connection is active approx 100s and closes with 200 status. If I disable DNS proxy it solves the problem. I`ve checked out the docs but I have found only the issues with buffering but not an interrupting.

Can I do something to solve the problem with DNS proxy? Or I cannot use SSE connections longer than 100s.

Thanks a lot!

I also have the same question

I resolve it with send a sse comment after connected.

Thank you for your answer. I will try
