Not able to reach login page

Hi all, from few days I am experiencing the problem where I can't reach login page. Here's the log output:

Could you help me understand what might be wrong here ? It was working correctly and then it just stopped. Thanks!

@mhzawadi how did you calculate the signature ? To be precise I think I know how to calculate, but what data is used to generate the signature and how to get it :)

[mhzawadi]

I didn't, I robbed it from my browser session.

I did have a look at some documents that are on other issues and couldn't work out how

[bboguszewicz]

Would you have the time and energy to briefly tell me how to do it :) ? I'm an embedded software enginner and lacking a bit of know-how in terms of web applications. I tried to find something in chrome console and the only thing I found was the signature.js, but couldn't find what I needed

[mhzawadi]

sure, you login to the foxesscloud site. open the dev tools (option+command+i on a mac), click the network tab and reload the page. scroll down the list of loaded files till you see access, click that and scroll to the bottom of the headers tab.

On a mac I can right click the signature and copy the value

Hope that helps you out

[bboguszewicz]

Thanks a lot I was able to find it, but still failing yet with fake requests. Will investigate further, thanks for the help :)

@bboguszewicz does this issue exist in the newest version v0.17?

[bboguszewicz]

Unluckily no, have a timeout on login page Timeout while fetching data: https://www.foxesscloud.com/c/v0/user/login

[bboguszewicz]

I have also checked on 0.18 and the issue is still in place for me. Just to let you know I have made a workaround by using two shelly 3em which gives me much more flexibility and granularity anyway, but of course if you would need any help with testing let me know :)
