[Error] Failed sending the icon byte stream as a response

maxin · December 9, 2025, 10:35am

System:

ASUS PN41 PE (PentiumSilver N6000 1.10GHz /8GB RAM/SSD) / WinSrv2025 Latest
OHv5.0.3, Temurin 21.0.9+10-LTS
Mosquitto v2.0.22, Z2M v2.7.1
PosgeSQLv17.6.2 (special items), rrd4j(supported types), mapdb (strings restore on startup)

After upgrading from version 4 to 5, I got this error.

The icon will be shown, but the logs often show errors like these. How can I fix the system behavior or remove this error from the logs? The error can occur for any icon.

I have this error in the logs when starting up.

I recognize these error messages. I sometimes have them too for unknown reasons.

If anyone can shine a light on this, it would help me also.

rlkoshak · December 9, 2025, 8:53pm

The log only appears during startup?

Do you have any MainUI, phone app, or sitemap up while OH is starting?

When a UI gets disconnected from the OH server, which happens when OH is restarted, it repeatedly tries to reconnect to the server. When it does it requests updates. But it might connect and request those updates before the OH server is ready to actually provide the answers. Errors can occur at that time.

If this error only occurs during start that is what I would guess is the reason. You’ve a UI that tried to request an icon before the IconServlet was ready to respond.

Anytime while OH working, Anyware while using MainUI or BasicUI.

Today I opened Sitemap with two items with identical icons - water_meter_2_cold. One icon appeared correctly, but the other item had no icon. The error logs reported an icon loading error. After reopening Sitemap, the error was gone.

I am also experiencing this error message. For me it happens when the openHAB IoS app is started, and it was also a problem in OH version 4.x

maxin · December 20, 2025, 4:51pm

I had this problem on version 5.0.2

maxin · January 11, 2026, 12:34pm

I had this problem on version 5.1.1
