I bought MikroTik hEX S (RB760iGS) and S-RJ01 copper 1 Gbps SFP module.
After few dangling (downgrading and upgrading) with different RouterOS versions due to hEX S getting link on SFP module problem (topic 137139), i finaly got it working with the latest RouterOS v6.43.2 (and latest RouterBOOT v6.43.2), and everything is working just fine, except every so and then (about 5 to 10 times in a day) in logs I get interface error that sfp lik is down, and after one second is up, like it resets itself for no apparent reason.
On the other side I have an Metal 52 ac (RBMetalG-52SHPacn on latest RouterOS v6.43.2) connected with 10m UTP CAT6e cable, that was connected to hEX (RB750Gr3) prior to hEX S, and had no link issues in that configuration.

Is problem with link reseting with hEX S hardware, or SFP copper module, or Router OS ?
