Hi Catalin,
I'd suggest taking a backup of your current switch configuration ( if you are using local management).
Then trying a factory reset , by following these steps from the 1930 user guide
If the SFP still does not work after the factory reset, I guess your options are to open a case with HPe support, or alternatively try "temporarily" reverting back to the 2.6 version of the firmware & verify the SFPs still work as they did before.
From what I could find, the 1930 supports these SFPs
Good luck,
Travis.
