Why might the SFP ports not work on the HP 1920 switch?

Question

Computer networks

Hello.
There are 3 offices in the industrial zone, between them there is an optics. Between the two were Gigalink media converters, and two old HP procurve switches (I won’t tell you the model anymore) with combo ports. I put SFP-WDM3.03 ​​and SFP-WDM5.03 Opticin ports in them, and plugged the patch cords - the network worked. On Saturday, a third new office was added, optics were also extended from it to the first office and a new HP 1920 switch and 2 more pairs of SFP ports of the same were purchased for the first office.
The old HP was put in a new third office, and the new 1920 in the first office, equipped with a normal switching room, into which, it turns out, 2 optics from 2 offices and the Internet converged, all this was planned to be connected to the switch via SFP.
I connect patch cords to SFP ports - the status is Disabled, there is no link, the port is seen as 1000Base-LX, in the logs the disconnection-connection of the port is fixed. If you connect an SFP and a media converter, the link indicator on the medic blinks quickly and often, and nothing else. What could be? SFP ports are connected in pairs correctly. But there is no link on them, but there is a link on doctors with the same parameters.
Tell me where to dig. Thanks to.

Go to the web face of the switch and see what is written in the logs. On my HP 2530-48G switches, the piece of iron did not accept any sfp converters other than native ones. When I tried to connect gigalink on my sfp ports, an orange diode started flashing, signaling that the converter does not support. Perhaps you have the same.
