I encountered to same issue. After looking through the code I believe issue is in the signalRHelper.ts file. I got this working by following change:
export class SignalRHelper {
static initSignalR(callback: () => void): void {
new LocalStorageService().getItem(
AppConsts.authorization.encrptedAuthTokenName,
function (err, value) {
let encryptedAuthToken = value?.token;
// qsAuthtoken set as undefined initially. Initialize it only when we have token available
let qsAuthToken: string;
if (encryptedAuthToken) {
qsAuthToken =
AppConsts.authorization.encrptedAuthTokenName +
"=" +
encodeURIComponent(encryptedAuthToken);
}
abp.signalr = {
autoConnect: false, // _zone.runOutsideAngular in ChatSignalrService
// autoReconnect: true,
connect: undefined,
hubs: undefined,
qs: qsAuthToken,
remoteServiceBaseUrl: AppConsts.remoteServiceBaseUrl,
startConnection: undefined,
url: "/signalr",
};
