Question

Hello.

RUT240, firmware: R_00.01.11.2, client connection via L2TP/IPsec with pre-shared key, and id secret: %any. Try 3G and 4G mode (no difference)

Encryption settings: AES128, SHA1, MODP1024

Mikrotik RB750Gr3 - Server L2TP/IPsec: default security settings: AES128, SHA1, MODP1024

Problem: teltonika first connection set encryption is MPPE128, after 30-40sec, reconnect and connect with AES128, then again reconnect after 50sec with AES128 and can reconnect again and after 3 or 4 time of reconnect works normal.

Please make a test with connection to mikrotik L2TP/IPsec server and investigate this problem

With RUT230 client L2TP/IPsec is no problem at all, connection established with first try and work stable.
