Error installing ZHA

Hi, i’m new with Zigbee and would like to migrate from a working zigbee 2 mqtt with a sonoff zigbee bridge pro with tasmota firmware to ZHA.
Tryed to follow some guides but didnt worked out. Since i only have 5 zigbee devices installed on HA removed the mqtt broker and zigbee2mqtt.
I tryed many times to install ZHA but after i select the chip of the coordinator (znp) and insert socket://my_coordinaror_ip:8888, 115200 and software, it asks if i wanna recover from a backup or install a new network.
Whatever i choose after 50 second i get a generic “Error”
During that time i can see on the Tasmota consolle that HA connects 3 times correctly
Havent found any clue on the homeassistant.log file (where should i look to debug the error?)

Anyone could help me?
Thanks in advance

Problem solved!
I was using the external address to add ZHA (duckdns.org btw)
Installed via lan using ipv4 address worked!
