redsmin-proxy can't connect to redsmin server

rscarvalho commented 9 years ago

I'm trying to use redsmin-proxy to make the bridge between my local redis server and redsmin, but I'm having no success. It keeps timing out and reconnecting in an endless loop. On redsmin UI I'm receiving this message:

This is the terminal output for redsmin:

Hello Rodolfo!

Have you tried to start Redsmin proxy in debug mode to see what was going on? Have you verified that you were able to access to ssl.redsmin.com.

rscarvalho commented 9 years ago

@FGRibreau that is the log in debug mode. I can connect normally to ssl.redsmin.com via openssl s_client and telnet.

FGRibreau commented 9 years ago

Hello @rscarvalho,

It's the first time I see this kind of issue, did you tested openssl & telnet from the docker/VM/server you run redsmin-proxy on? Do you use docker to run redsmin-proxy? Are you sure catnpm bin -g/../lib/node_modules/redsmin/etc/redsmin.json is configured correctly?

What is your server-ip? Our firewall could also have blocked it (it would be the first time though)

I have the same issue. It was working fine until I updated redsmin-proxy to latest version and now it can't connect.

What can I do to help with debugging this?

FGRibreau commented 7 years ago

@kop do you still have the same issue ? Did you try to launch redsmin-proxy with DEBUG=true environment variable ?

kop commented 7 years ago

@FGRibreau, no, I don't. I think this issue is related to Redsmin server. Probably client just does not print correct error when ssl.redsmin.com is not working properly.

FGRibreau commented 7 years ago

Hum it definitely works we have checks around the world every 5 minutes to ensure Redsmin-proxy works and I just verified locally with redsmin-proxy latest version on nodejs v8.

What version of nodejs & redsmin-proxy are you using?
From where are you trying to connect to Redsmin? (a corporate network maybe ?)
Did you try this?

I'm experiencing this same issue. redsmin-proxy is successfully negotiating the handshake on one AWS EC2 instance but not the other. The servers are in two different AWS accounts, and I'm trying to connect each to a different redsmin account.

Log excerpt:

Common specs for both servers: OS: 64-bit Ubuntu 16.04 redsmin-proxy@4.0.1

Things I've tried:

Changing my node version. The working server uses node 6.11.2 and npm 3.10.10. On the server that isn't working, I tried node 8.6.0 / npm 5.6.0 and node 6.11.2 / npm 3.10.10. Both version combinations resulted in the logs above.
Using openssl to verify connection to ssl.redsmin.com:993 - I was able to connect without issues
Using DEBUG=true environment variable when running redsmin - no change in the log output

Neither server has any iptables rules configured:

$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Any thoughts here? There don't seem to be any significant differences between these two servers.

nickvoegeli commented 6 years ago

Strangely, I waited two days, deleted that server from the redsmin GUI, and started over, and it worked the second time. No idea why.

FGRibreau commented 6 years ago

@nickvoegeli sorry for the delay, it seems really weird indeed. There might be some connectivity issues between your AWS instance and us. Be sure to setup a process runner on top of redsmin-proxy to handle disconnections

pankajjha-cd commented 3 years ago

This is exactly happening with me. I am running Centos 7 with Node v12.20.1

I am having the same issue, I have been using redsmin almost a year and today after I killed all node aplications and restarted redsmin started to get below error: My IP is: 46.1.214.116 Redsmin KEY =624ee2fdcfcf3810486bd1fc
