Hello there,
Case Id #04931594
I have a backup job which was going seamlessly. but in the last days it was failing after reaching 80% with error message attached below. I tried the job by disabling firewall rules nothing new occurred. All backup infrastructure components are working fine for other VMs. I have also checked firewall logs but there is nothing blocked related to this backup.
[EDIT by moderator]: removed log sniplet as stated in the forum guidelines
I need to figure out how to resolve this issue immediately.

Re: Error: Unstable connection: unable to transmit data. Failed to upload disk
Hello,
and welcome to the forums.
Looks like something is blocking the connection.
Thanks for your understanding,
Hannes
and welcome to the forums.
Then I recommend working with support. Support can analyze logs, they can give proper answers. It makes no sense to speculate on a forum (forums are mainly run by product management, not support).I need to figure out how to resolve this issue immediately.

Hello Hannes,
Thanks for the reply. Can you suggest If there is any way that points me to the place where the bottleneck is appearing. I tried to capture some packets using Wireshark and i noted a tcp-keep-alive failure. does it imply something???

Hello,
in the logfiles (c:\programdata\veeam\backup) there are IP addresses / DNS names where the errors happen. TCP connections can be checked with any tool you like (telnet, powershell...)
Best regards,
Hannes
