This issue still exists in version 2.2.19.8f6a283

Check your mqtt config. Are you running a private server with a cert for this?

[zarya]

Yes i am, server used is EMQX the cert is self signed first connect after reboot it works flawless but after it reconnects wifi it stops working and trows the mem allocation failed msg.

Same here: T-Beam v1.1 SX1268 433/470Mhz

Trying to connect to a public MQTT server in Brazil:

Already tried v2.2.19 and v2.2.17, both have this problem.
