I cant align my sequences，the website appears completely inaccessible

Hello!
There is something wrong with my software.Alignment is written in gray on the web server and it is not clickable.
The website(https://www.compbio.dundee.ac.uk/jabaws/ServiceStatus) appears completely inaccessible, and there is no error message. I have tried different browsers (Chrome/Firefox), devices (different PC), and networks (home/work), but none of them worked. Could you check if there is an issue with the server?
Here is my java console log:
ava.net.ConnectException: Could not connect to http://www.compbio.dundee.ac.uk/jabaws/MafftWS?wsdl. Is the server down?
