Hello,
I have issue with winbox v2.2.18 connect to my router(RB951G-2HnD) with error: “Bad File Format”.
I had the latest routerOS 5.x and everything worked OK(except flow control, what was the reason to upgrade to v6). Then after upgrade to v6.18, I wasn’t able to connect to router with the error: “Bad File Format”. Web access was OK. Surprisingly, winbox v3.0beta3 connection is possible(not stable, I assume because of beta). So I thought it has something to do with upgrade issue and I waited for the next release.
Now, after the next upgrade to 6.19 the issue persist.
Please, does anybody have idea what can be the problem and how to solve?
