Can't connect to Wifi network secured with long PSK

[crtxcr]

Device: BQ Aquaris E5.4 Ubuntu Edition

I just got this device and wanted to connect to my WPA2 WiFi network which happens to have a 54 characters-long PSK. However, after entering my password (which naturally takes a little while) and clicking on "connect", it just simply returns me to the overview of WiFi networks near me. No error message.

The following askubuntu.com questions appear to be related to this problem:

I have enabled developer mode and edited the network manager file in /etc/NetworkManager/system-connections/ using adb shell. After that, I was able to connect to my network.

Steps to reproduce:
1. Set up a WPA2 network and give it a long password
2. Click on your SSID on the list
3. Enter your password
4. Click "Connect".

Expected result:
Connected to the WiFi network

Actual result:
You see the list again and no indications that you are connected to the network. You aren't connected to the network.

Status changed to 'Confirmed' because the bug affects multiple users.

I have the Problem with a 63 charter long password
with OTA10.1

A workaround is to copy and paste the password from a different app. I created a note with the password as a title and copied it from there.

Workaround by @8-mail-g worked for me. This question http://askubuntu.com/questions/597333/get-wifi-password-into-ubuntu-touch suggests it's because of a timeout occurring before the password was entered. Maybe on the coding side, this can be prevented by saving the password temporarily and retrying the same password a second time upon a single failure, if the reason for failure was a timeout?

I had the exact same problem with a much less complex password that was comprised of 8 mixed case characters followed by and underscore which was followed by 4 numbers

Cccccccc_dddd (just the format, not the password)

Copying and pasting worked great and it connected first try.
