I put together a Ryzen 9 5900x with a msi B550-vc 32g ram and flashed the sfxos on the usb. I found the ip adress with the angry ip scanner,when i type that ip to log on to rig to change the mining adress to mine i get this message: err\_ssl\_version\_or\_cipher\_mismatch. Therfore i cannot log in to rig to change mining adress. Has anyone ran into this issue? ---

Sorry mate, I have never used SFXOS. But there is a support thread at [SFXOS: Safex Cash mining operating system support](https://forum.safex.org/t/sfxos-safex-cash-mining-operating-system-support/7010) that may give you some insight. ---
