Hi @mukeshtalks, sorry for the delayed response. Can you capture the Serial output and post the part where you set the URL?

@matth-x sorry for the late reply I am setting the URL through the web interface.

The log is below

@matth-x please help me i have shared the log in my last post and way i am configuring the webs socket URL

The device loses the configuration between the boot sequences. Everything looks okay at the first boot and at the second boot, so the error could originate in between. Can you search for more debug messages (starting with [AO] ERROR)? It could, for example complain about flash memory shortages or other file system errors which could damage the URL store.

Generally, the SECC example was just intended for proof-of-concepts. After all, the integration of WiFiManager is not the best and I would advise to write an own maintenance portal for productive use (WiFiManager or another project, at your choice).
