What switch version are you using? Can you share more about the connectivity of the switch as well?

Hello, I am trying connect 2 switches with fiber.
The first switch is HP 1820 24G and second is Aruba 1830 24 ports (JL812A). In both switches I am using this SFP Transceiver J4859D. On 2nd switch I am still getting port suspended by link-flapping and I can't find the reason why. I tried almost every setting, Spanning Tree is OFF and I don't understand why it is not working. Can someone help me? Thank you.
