Im trying to establish a server socket on Matlab2020a.
However when I try to open the socket, it seems to be stuck at that line.
It was working till a few days back, but keeps getting stuck at this point now.

The following code will create Server socket at port 5001 and infinitely allows clients to connect and receive data from them:
[~,hostname] = system('hostname');
hostname = string(strtrim(hostname));
address = resolvehost(hostname,"address");
server = tcpserver(address,5001,"ConnectionChangedFcn",@connectionFcn)
function connectionFcn(src, ~)
if src.Connected
disp("Client connected")
readData = read(src,src.NumBytesAvailable,'string');
disp(readData);
write(src,"Bye Bye","string");
end
end
Client code(for testing purpose):
client = tcpclient("172.31.120.98",5001,"Timeout",5);
% do change Ip address to Ip address at which server socket is created, you
% can find that from command line after runing server socket code
while(true)
rawData="Hello Server";
write(client,rawData,"string");
rawData = read(client,7,"string");
disp(rawData);
end
