thanks in advance.

you should not using proxy_redirect off;. want change redirects

location /phpmyadmin{         proxy_set_header x-forwarded-host $host;         proxy_set_header x-forwarded-server $host;         proxy_set_header host $http_host;         proxy_set_header x-ssl on;         proxy_set_header x-nginx-proxy true;         proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;         proxy_pass http://127.0.0.1:8080/phpmyadmin;         proxy_redirect http://127.0.0.1:8080/ $scheme://$host/;         proxy_redirect http://localhost:8080/ $scheme://$host/;         proxy_cookie_domain 127.0.0.1 $host;         proxy_cookie_domain localhost $host;     }
