my website posts forms on http but not on https - forms

Question

hello I'm in the process of converting my HTTP website to https but after getting https to work no post request from forms work
I have looked around a lot but nothing really describes what I have going on here, I doubt it nginx because when I start burp suite and make the website server HTTP it sends a post request like usual, but when I run it on https the post request isn't even sent doesn't show anything on the burp suite logs
<form action="" method="post" autocomplete="off">
<p><input type="text" name=username id="username">:username
<p><input type="password" name=password id="password">:password
<p><input type="checkbox" name = "rmbm" id="rmbm">
<label for = "rmbm">remember me</label>
<p><input type=submit value=Login>
forgot password?
</form>
this is my form but I don't even see a post request
I should see a post request but I don't on burp sute
update:
hello, I've just had an epiphany. could it be the service worker and yes I was right after unregistering the service worker it worked perfectly so the problem is the service worker.
knowing this I will post the code
my service worker:
console.log('Hello from sw.js');
'use strict';
var cacheVersion = 1;
var currentCache = {
offline: 'offline-cache' + cacheVersion
};
this.addEventListener('install', event => {
event.waitUntil(
caches.open(currentCache.offline).then(function(cache) {
return cache.addAll([
'/static/html/offline.html',
'/sw.js'
]);
})
);
});
this.addEventListener('fetch', event => {
console.log("fetching");
if (event.request.mode === 'navigate' || (event.request.method === 'GET' && event.request.headers.get('accept').includes('text/html'))) {
event.respondWith(
fetch(event.request.url).catch(error => {
// Return the offline page
return caches.match('/static/html/offline.html');
})
);
}
else{
event.respondWith(caches.match(event.request)
.then(function (response) {
return response || fetch(event.request);
})
);
}
});
now looking at my code it just dosnt handle post request
so i will try to fix this on my own
