Unwanted delay before "Attach Browser" activitiy

Before “Attach Browser” activity a delay of about 10 seconds occurs. It happened in another part of my process and I could solve it by using a workaround. But this time I’d really like to know what would cause it ie., what would be the root cause of this problem. Does anyone can give some plausible explanations?

Thank you!

PS : Since there is delay in no other part of the process, please do not say it is about the Internet network :slight_smile:
