DigitalOcean droplet server does not work

Summary

smp-server binary from the release page with BuildID cd99e16fec87f49fbfc352350b688e9f90f36e56 DOES work.
smp-server binary from the DigitalOcean droplet with BuildID 9dcbeeef5875acc615c486a4c55be8b125592628 DOES NOT work.

What i did

I used the simplex digital Ocean droplet and run it.
Then i downloaded the simplex-chat (client application) and tried to connect it to my new server (running on digital ocean).
unfortunately this did not work. I got the following error message:

me@mybox:~$ simplex-chat -s smp://tXC4IMc1KUOAEYfXwX+S9ACu2EEitBlSxqCObdKDBEU=@simplex.scusi.io
option -s: @: Failed reading: satisfyWith

How i found out

When i tried the same thing with one of the offical server, it works.

I downloaded the server binary from the release page and started it locally on my computer.
I connected to my local instance, did work, as seen below.

me@mybox:~/$ simplex-chat -s smp://h9ZEZW7uiweKkT6DtExxo5JI9mgyGjc1vSp8wBHaGaE=@127.0.0.1
SimpleX Chat v1.0.0
db: /home/me/.simplex/simplex_v1_chat.db, /home/me/.simplex/simplex_v1_agent.db
type "/help" or "/h" for usage info
[...]

Next thing i did was to check if the local server binary is the same as the one in the digital ocean droplet.
Turns out it is not.

root@simplex:~# file /opt/simplex/bin/smp-server
/opt/simplex/bin/smp-server: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=9dcbeeef5875acc615c486a4c55be8b125592628, stripped

The local server binary (downloaded from the release page) is different from the above.

me@mybox:~/Downloads$ file smp-server-ubuntu-20_04-x86-64 
smp-server-ubuntu-20_04-x86-64: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=cd99e16fec87f49fbfc352350b688e9f90f36e56, stripped

After finding out that the binaries from the release page and the droplet are different i just uploaded the release binary into my droplet and overwrote /opt/simplex/bin/smp-server.

After replacing the smp-server binary from the droplet with the one from the release page it also works for me with my digital ocean droplet. I think the digital ocean droplet needs some love and a binary to be updated.

P.S. Thank you for that software project, i like it.

Start by comparing the release-page smp-server binary with /opt/simplex/bin/smp-server on the DigitalOcean droplet, using the BuildIDs and the reported simplex-chat connection behavior. Check how the droplet obtains and installs its binary; done means the deployed binary matches the intended release and the reported server connection succeeds.
