Red Triangel / Connection failed

Hello, since last Friday we have been having connection problems with two accounts. Nothing helps…
We use 9 different accounts and only two have this problem. Could someone be so kind and help us. We are a young, small start-up and not fit in IT matters.

Click the “dropdown arrow on the right of Refresh” at the top left and click “Show Operations”. Then click the “Log tab” and look for any obvious errors and paste them in this thread.

Blank out any personal details.
