Hi @dcepu, thanks for reporting this issue! Do you experience the same problem with previous versions of the agent, such as 3.236.1?

[dcepu]

@aleksandrlevochkin The agent's version was 2.217.2 and I had the same problem. I have updated it to the newest, 3.238.0, and the problem still occurs. I haven't tried the 3.236.1 version.
