Spark Notes Error

I have one user who, no matter the system, logs in to Spark 2.6.3 and goes to Actions - View Notes and gets immediately logged off “due to connection error”. Only user out of 2000 in our system,. Any ideas?

Is this happening with a fresh Spark profile also? You can try the latest Spark version http://bamboo.igniterealtime.org/artifact/SPARK-INSTALL4J/shared/build-665/Insta ll4j/spark_2_7_0_665.exe
