Which Meteobridge platform are you using?
Did you try the newly introduced "Proxy SFTP" option (released September 30)?

I am running Meteobridge on a Raspberry Pi 4B rev 1.5 using the
meteobridge-rpi4-v1.4.bin image. I got it a month ago. Prior to that I was running a TP-Link TL-MR3020 since 2019.
My old webserver where SFTP Upload worked fine from both the TP-Link router and the RPI 4B was a Raspberry Pi 2B running Raspbian buster.
My new webserver where SFTP Upload gets the error
Expected sha1!! from Meteobridge running on the RPI 4B (haven't tried the TP-Link router) is an Orange Pi 5 Plus running Armbian bookworm. So this is the latest Debian release (bookworm) vs buster which is two releases ago. The part that's so baffling is the Test SFTP button successfully uploads the test-upload file with no error.
I did try Proxy SFTP. I get this error:
Error: SFTP connect to k7rmk.com via port 2051 failed. (no more tries):

I don't know if this is related or not but when I got the new webserver, I did have to update PuTTy and WinSCP on my PC to the latest versions because I was getting the following error when I tried to connect via SSH and SFTP:
