I recently got hired into a new job, it is a junior developer position which matches my previous work experience. As I began my work, I was told there was some installations to be done in the server, I have never done something like this before but I kindly accepted the duty and went ahead to try and get the server to work except... it has been two weeks now and I can't get it to work, of course progress was made but the bare reality is that it's not working as it should yet.
We are in an agile team so I talked about my difficulties every day in the daily scrum and my project manager kept on telling me to "keep on trying" and I keep on trying everyday and right now I am sure reached the end of all ideas I could have tried out. I soared the internet, read the whole technical documentation, I even asked around other work-environment acquaintances if they could help me or had any knowledge about it, but they did not and I am the only one developer in our team. Recently I told the team this was a roadblock and I was out of ideas but everybody was calm, the project manager didn't seem worried at all with no progress being made except I am worried, I am very worried.
In my team there is nobody else with the same technical knowledge to help out, but it's a big company and my manager has many other teams under his supervision, so I am considering explaining the situation to him and asking if he can assigned somebody else to help me out with this problem since the project manager is failing to help. Is this an acceptable approach? Or should I just keep on trying and trying on my own until eventually I have a prophetic idea that will solve everything?
