Login issue from postman

I got a login issue while logging in to RT from the postman. When I tried to log in it showing the error “Your username or password is incorrect”, but I could log in from the browser using the same password and username. Can someone please help me to solve this issue? I am adding the request which I send from the postman and its response below

request : https://rt.reflectionsinfo.com/?user=chatbot.user&pass=Ch123$btu%23$
response:

<title>Login</title>

Shouldn’t you be hitting one of the REST APIs? This is just the normal web login

Yes, this one is for login into the RT site. Is this issue happened because of the special characters in the password? I tried with another username and password which is having only @ as a special character. And that works from the postman. But when I tried with the above-mentioned password and username from the postman it’s not working.
