We get a similar wave of errors every few hours:

Did the path change with some version? Probably it is when the browser cache is not cleared properly, respectively the asset not invalidated. Or, probably more likely, it is some dumb bots that keep scanning for resources they once found. I mean we have thousands of visitors and dozens of posters between two such log sets, so it doesn’t seem to be a general issue.
In our case access is done via proxy outside of the container and UNIX socket, hence no client IPs visible to check. For 77.208.167.253 I couldn’t find any relevant info, whether it is a bot or not.
