[SOLVED] Error: error trying to connect: error connecting to <ip> - TCP connect error: deadline has elapsed

[Darkniss]

We have a cluster of various nodes set up in our workspace, and we are trying to set up a back up server. When I try to back up I get the following error. I already tried setting up a new datastore. Still nothing. Any Ideas?

I also noticed when im making a back up job, pbs avail and capacity are at 0. How could I fix that?

looks like the network to the pbs is not stable?

Its connected to the network, I can ping to pbs on my network too

can you connect to 8007 in a timely manner? the error:

INFO: Error: error trying to connect: error connecting to https://192.168.0.101:8007/ - tcp connect error: deadline has elapsed

says that it runs into a timeout while trying to connect

I made some changes adding 8007 to the firewall because I thought maybe the port 8007 was being blocked still nothing. I ran curl -v https://pbs:8007 on one of the nodes in the cluster and I got a SSL certificate problem. Any Ideas?

does your firewall anythings special? it must let http2 pass through for the backup api to work

To my knowledge, it's not blocking http2, but I did notice that when I was using proxmox my cluster does show it using http/1.1

the "normal" api uses http/1.1 only the backup/restore api of pbs uses http2

If im running proxmox virutal enviorment 6.3.2, and have proxmox back up server 2.0 would that be an issue connecting?

while that should work fine, i still recommend upgrading to at least the latest 6.4 there may be some bug fixes in the backup-client. an upgrade to 7.x would be even better. also note that 6.4 support ends sometime this year

I got the issue fixed, The issue was I was connecting the pbs to one of the vlans, so what I did is got an ip from the cluster and applied it to it statically. and I was able to see it on my virtual environment. Thank you for your help!
