in order not to log IPs (GDPR) and also to prevent spread of errors in Sentry logging as IP/Port combinations are unique per connection and therefore will spam with many unique errors. By removing the unique information from the error the errors should be groupable again. Signed-off-by: Knut Ahlers <knut@ahlers.me>
