hi @Rainking80
i can not reproduce this.

please try the following:
disable all api queries to the opendtu before makeng the ota update, and check whether you have downloaded the correct version and .bin file.

note:
as your opendtu is at the deprecated generic pio environment,
see: https://www.opendtu.solar/firmware/flash_esp/#download-firmware

or if above does not work for you,
you might consider:

• make a backup of your config.json and pin_mapping.json
• connect your dtu via usb to your pc or mac
• visit the community webflasher https://solar.metacontrol.eu/opendtu_webinstall/ and perform an up/downgrade install as seen at the screenshot below.
• your board will be automatically detected, and the correct .bin file will be chosen automatically.

greetings,
metachuh

I have a somewhat similar error. I'm running 24.4.12 and want to upgrade to 24.5.6.
During the upload of the firmware, the console shows:
POST http://192.168.0.200/api/firmware/update net::ERR_CONNECTION_RESET app.js:77

It fails repeatedly with multiple browsers

After a restart of the device, the firmware upgrade succeeds.
