Did you build nacos in windows and run it with sh startup.sh?
You got this Algorithm HmacSHA256 not available error because your app cannot load the Java security libs correctly (So you cannot using JDK's own encryption and decryption algorithm).

See this line in distribution/bin/startup.sh:

JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext"

In windows environment, using : you cannot successfuly load the ${JAVA_HOME}/jre/lib/ext dir. Change : to ; in windows; or just delete this line, so it can use JDK's default dir.

JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${JAVA_HOME}/jre/lib/ext;${JAVA_HOME}/lib/ext"

Can you check the -Djava.ext.dirs value in your startup command output?

[ManuRodgers]

[zarkzheng]

I see. In version 2.0.3-SNAPSHOT that you used, they change the shell from JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext" to JAVA_OPT_EXT_FIX="-Djava.ext.dirs=\"${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext\"", in order to Fix the problem of startup error when the JAVA_HOME path contains spaces under Linux/Unix/Mac system, see #6335.
Could you try remove the \" around and just change to JAVA_OPT_EXT_FIX="-Djava.ext.dirs=${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext" and try again? It should be work then.

[ManuRodgers]

it is still not working after I removed \" .

[ManuRodgers]

Perhaps, I can use other versions of Nacos to avoid this issue from happening?

[zarkzheng]

But I can still see the " behind -Djava.ext.dirs= in your console output.

You may need rebuild your project.

[KomachiSion]

Can you make sure whether #6409 can fix this problem and whether #6335 cause this problem? If can't fix this problem, please close #6409 and submit new PR to revert #6335.

[zarkzheng]

@KomachiSion Yes, I am pretty sure #6409 can fix this problem, and i checked on both Ubuntu and Windows.
The correct output should be :

## CORRECT
-Djava.ext.dirs=JAVA_HOME/jre/lib/ext:JAVA_HOME/lib/ext

but not this one :

## ERROR
-Djava.ext.dirs="JAVA_HOME/jre/lib/ext:JAVA_HOME/lib/ext"

And based on #6335 , 6409 also can handle the JAVA_HOME path which contains spaces now.

After removing that double quote, everything works. Thank you guys for your help and patience.
