I always receive connection lost when trying to upload files bigger then 700MB when the code works perfectly with smaller files . I tried the upload\_mas\_filesize in the input tag in the template node and nothing changed I am new to node red so i couldn't understand the problem if anyone has faced the problem before can help me Thanks in advance. ---

Which node are you using to upload the files? node-red-contrib-ui-upload? if yes did you used also node-red-contrib-chunks-to-lines ? Can you give more info like an example flow and picture? ---

I am using the input html tag here is the code for the dashboard template am then encoding the file to send it inside a HTTP put request body ```auto [ { "id": "c881b02b7b31fbf0", "type": "ui_template", "z": "64a9f9c7f717adab", "group": "ffb7763e.5afd68", "name": "upload html webpage", "order": 2, "width": "12", "height": "43", "format": "\n\n\n \n\n\n\n\n \n


\n \n Click to send the files\n \n \n\n
\n \n
\n \n \n \n
\n \n \n\n\n", "storeOutMessages": true, "fwdInMessages": true, "resendOnRefresh": false, "templateScope": "local", "className": "", "x": 280, "y": 320, "wires": [ [ "1736b8eafc33579b" ] ] }, { "id": "ffb7763e.5afd68", "type": "ui_group", "name": "Home", "tab": "ba3634a0fa711e8c", "order": 1, "disp": true, "width": "12", "collapse": false, "className": "" }, { "id": "ba3634a0fa711e8c", "type": "ui_tab", "name": "Home", "icon": "dashboard", "order": 1, "disabled": false, "hidden": false } ] ``` ---

the solution is to divide files to chunks when reading them in the template node. ---
