Directing root requests to sub-url and double slashes - nginx

Question

So, in my app, I want anything with root url ending with / to go to /pss
#user nobody;
worker_processes 1;
#error_log logs/error.log;
error_log logs/error.log debug;
#error_log logs/error.log notice;
#error_log logs/error.log info;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
server_name_in_redirect off;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
# Enable Gzip
gzip on;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_min_length 1100;
gzip_buffers 4 8k;
gzip_proxied any;
gzip_types
# text/html is always compressed by HttpGzipModule

gzip_static on;
gzip_proxied expired no-cache no-store private auth;
gzip_disable "MSIE [1-6]\.";
gzip_vary on;
server {
listen 80;
server_name localhost;
#charset koi8-r;
rewrite_log on;
access_log logs/host.access.log main;
index index.html index.htm;
location ~ ^/pss/?(.*)$ {
root /opt/tech-ui;
rewrite ^/pss$ / break;
rewrite ^/pss/(.*)$ /$1 break;
}
location / {
root /opt/tech-ui;
}
location =/ {
rewrite ^/(.*)$ /pss/$1 break;
return 302;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
# HTTPS server
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
daemon off;
So, whenever I out in localhost I get localhost//pss
I'm super confused, I've googled around, and I'm not sure what to do next, I know I'm missing something basic in nginx.

You can use rewrite rules bellow:
location = / {
rewrite ^ /pss&$args last;
}
or
location = / {
return 301 http://localhost/pss;
}
